KA problems

[Z_Ro_01]

Hey guysI have a 1992 240I decided that since I had S14 intake manifolds that i would switch them outI did, S13 to S14 intake manifolds both upper and lower.Problems:Now when I start the car it doesnt want to stay onit TRIES to idle at around 200-400 rpm but obviuosly not enough to keep it running and then turns off but I can give it gas to stay onAlso, when I give it gas it revs very nice but it sounds like i have a damn turboim guessing its a vac leak, a really big one?And also, after pumping my breaks a bit there stiff as hell now, im guessing its beacuse of the brake booster? maybe its not conneced right?

can you guys help me outits been one hell of a long day

thanks guys

[Z_Ro_01]

Oh yaand I think something is wrong with my coolant temp sensor ( the little red one off the upper plenum)The car gets hot but it reads inside as if it cold, so ya, could this be causing some problems also?

[neverlift]

yeah sounds like a big vac leak. As for the cts yeah they f*** with everything. If your getting poor fuel consumption,or it feels like vtec kicking in at 4000rpm its ba or going bad quick.

If you dont mind me asking why?

[Z_Ro_01]

why what?lol

changing the manifolds?well...long story short, i had a S14 engine with ALOT lower miles and i cleaned everything out all nice and shiny, and I was fixing a vac leak with the other manifold, i dont know why i did the trouble of changing the lower intake plenum but i was all into it, i think im going to go back to the S13 one, but hellany suggestions as of where the HUGE VAN LEAKS are coming from?and where could i get a new CTS?and would the CTS cause my car to run like **** even when it isnt moving?

oh and also, wtf is wrong with my brakes, the pedal is like a rock, it worked when i first drive it and i was comming back home and the pedal got super stiff all of a sudden, what is it?

[ka24e510]

you definitely have a huge vacuum leak and that is why you have a problem with the brakes, and the runs like shiz. the sensors for the s14 are not the same as the ones for the s13 so going back to the s13 lower manifold is a good idea. now that you dont have a swirl valve (little flappers in the old manifold), did you unplug the solenoid so that it does not leak? also, most people forget the pcv hose that is very hard to see, but that is usually left unplugged and a huge leak, it is located as a u shaped hose from the timing cover pcv port to a big pipe under the manifold. also check the vacuum line from the brake booster all the way to the manifold, i dont mean look at it, stare at it and feel it while running to see if there is any cracks/leaks like at the plastic valve or a vacuum T. let me know what you find,

[Z_Ro_01]

Well i know the S14 sensors are not the same thats why i changed it sout and used all my S13 sensors and bolted them to the S14 lower plenum

What solenoid are you taking about? beacuse im using the S14 upper plenum and im not using the butterfuly valves any more

Yup, i plugged the PCV hose and everyhting but im going to double check it in the morning and see if its all connected good

also in the morning im going to check the BB vacuum line and see if I feel a leakI was thinking could it be the brake booster or the check valve?

Also im going to see if i can find a new CTS beacuse im guessing mine is broken beacuse i was stupid and twisted the little red connecter instead of the hole thing, could the CTS cause SUCH BAD IDLEING?

pretty much its like thisthe car turns on and revs itself to 3k then goes to >1000k and then tries to idle at >500rpms and then dies, its fine if i give it gas though, WHEN i give it gas though, it souns like a damn turbo spoiling up, literally, and im not turboed, its weird but it only makes the noise when i get off the throttle.

should I also check all of the intake mani bolts? upper and lower?

Thanks guysseriously appreciate it, it sucks not being able to drive your DD when you work

[Z_Ro_01]

okwell I checked the manifold and noticed the PCV was wasnt connectedso i reconnected everything and changed the S13 PCV with an S14 one

well now the car turns on runs a bit worseno more LOUD turbo noise when the throttle isnt pressed

BUT, when the car turns on it still revs itself to 3k then it just goes all the way down till it dies, it doesnt idle at allwhen i press the gas the car revs up to around 4k-4.5k by itself? I dont hold throttle in long enough for it to rev that high

and the brake pedal is still stiff as a rockI didnt get a chance to check the brack booster line cuse the wont stay on that long

Can anyone PLEASE HELP MEthanks guys-Jon

[neverlift]

inspect the bb line visually and go ahead and take a screwdriver to the clamp to be sure its tight,make sure you didnt get a crack/hole in the line,honestly you could have damaged several lines while removing/installing parts if they are old and brittle.

side note< you did use NEW gaskets and the proper torque and sequence on the bolts/studs right? That could cause some vac leaks if done incorrectly.

is the IACV hooked up(electrical/vac)

[Z_Ro_01]

yupI used new gaskets and bolted everything in sequenceand ya, the IACV is hooked up, dont know why it seems the car doesnt even have one though

dammittomorrow i think im going to switch over the S13 lower plenum back and see if that fixes anything

any one else have any other suggestions of what it could be?

[DjPantsSpecR]

i fairly certain i know what this is.

you already told us you can ehar a HUGE vac leak, thats what you eman by the "turbo noise"

however, this is so very common, and i fought with it for around an hour yesterday:

i'm guessing you have a vak leak around the big rubber o rings that seal the injectors to the manifold. they are hard as hell to seat sometimes.

if you can get someone to help you to keep the car idling, stand outside it in the bay, and use a length of hose to lsiten in specific areas for leaks. you'll know when you find it.

however, im fairly certain thats where you leak is, i went through the exact same stuff yesterday getting my custom manifold running.

so go check that out and lemme know, if thats not it, using the hsoe will help you.

[Z_Ro_01]

AlrightyI double checked the injectors and i figured out there were not sitting right well i rebolted everything and made them sit rightnow the car actually runs and i drove it today, not bad at all only problem nowSOMETIMES the car idles at 800-1k then drops to >500rpm and tries to die out, still tryin to fix that...any suggestions?

Also, my car isnt reading the temp, the temp gauge stays cold the whole time, could it be the little temp plug thing? and how do you when the CTS is bad?

other than that the car runs pretty good now except for the exhaust leak, lol

also, off the topic of the enginei tried to take out the damper box for the clutch and one of the lines wouldnt come off, the bolt rounded off ( the one that connects to the line that connects to the slave. Any suggestions on what to do now cuz im really not feeling bleeding the car, ive already started anyway but i havent gotten anywhere in the past 2 and half hours....

[DjPantsSpecR]

damn im good. i'm sorry i didnt read your post earlier.

that other thing is a vac leak too, but its usually due to a vac leak in a hose in the enormous tangle of vac lines. i would suggest checking the large vac ling coming off the bottom of the EGR's BPT valve. it makes a 90 degree bend and it commonly fatigues out.

you accidently swaped in the wrong temp sensor into the upper manifold. its the little spade connector, not the big plastic one. try swapping it and see if that works. it should

it'll sound a lot better when you seal that exhasut leak. if its at the exhasut port it might even help a little, but i owuldnt bet anything on that.

i would put a big bad vice grips on that bolt.

[neverlift]

fvcking injector seals are a *****,I had a nasty lean condition brought on by that shizzle.(unmetered air) good job dj

dj start a thread or dig up the old one I need a pic of that manifold!!!!!!!!!!!!!!!!!!!! **** email em if you want just show me damn it.

[DjPantsSpecR]

i will, its not pretty, but you'll still love it. i'll take a poopy pic for you later.

total cost of build: 63 dollars. and one spun bearing.

[Z_Ro_01]

thanks guys for everythingfinally got most things fixed

lol, vice grips DIDN'T WORKim going to drill through the little bolt part and use that to do it sometime soonhope it works, lol

and i bought this exhasut sealing crap that i saw, hell imma try that, the leak is right where my hotshot headers meet the cat.

but again thanks guys

[Z_Ro_01]

Hey guysI got all the old problems fixed

Now I got something new

I drove my car around yesturday and it worked just fineI got in my car and tried to turn it on and it took a couple of triesI then stopped agian somewhere and when I tried to turn it on agian it wouldnt turn on.

It cranks over, it has enough batterywithin the first 10 times i tried cranking it it caught for about 1/2 a second then died, that happened about two timesnow it wont even do that anymore, it just keeps on cranking but not starting

Anyone got any suggestions?Im kinda thinking it could be the fuel pump but I dont know

The car has 198K on it

[DjPantsSpecR]

hot start condition right?

when you're starting it, hold the pedal to the floor and lemme know if it helps you start.

when was the last time you replaced the coolant temp sensor?

[Z_Ro_01]

The very first time it wasnt a hot startbut it turned on after a couple cranks

When I tried cranking it agian after i drove it ( hot start)wouldnt start period

Tried it agian this morning (cold)didnt start

It cranks over with no problem, but it wont start

[Z_Ro_01]

I tried holding the pedal down but that didnt do anything

And I havent ever replaced my CTSCould that actully cause my car to not start on a cold or hot start?

Ive thought the whole time it was a fuel problemBut Im not sure

[driftsiidwayz]

hey i got that same problem.........i was stumped for awhile...but i fixed it here it goez..........first check ur knock sensor make sure its not cracked...then replace the coolant temp sensor..........and it will work again...just make sure throttle is cleaned....check tps..........make sure you have all the proper items like new spark plugs wire , rotor, spark plugz..........make sure everything is proper....but i know the temp sensor has to deal alot with the car shutting down and hesitating when driving.....or stalling shutting down..........coz the temp sensor all dealz around the egr.....so check check check...................=)

i think this should help

[Z_Ro_01]

I'll check the knock sensor when I get a chance

But the car doesnt hesitate or shut down while im drivingwhile the car is on it runs fine, its only since I turned it off, it wont turn on agian

still think it could be the CTS?

[Z_Ro_01]

Anybody got anything?

[driftsiidwayz]

does it crank ?

[Z_Ro_01]

Oh yait cranks perfectly

but it just doesnt start

[driftsiidwayz]

needs new starter

you should check........

i know for sure its starter...coz my old s13 did the same thingso i replaced it and it worked

[Z_Ro_01]

AlrightI got it fixed (for now)

It was just my fuses, my fuel pump relay and my fuse The relay was being shorted and the fuse is messed up in itself

I got some help and we figured it out

Im still kinda scared though...I put a new fuel pump in and it used different wires so i cut and crimped it, and im kinda feeling weird about crimped wires being in the fuel tank with gas...ehh...any suggestions ??

Thanks for all the help AGIAN guys

And no it wasnt the starter Could have been it though with no problems

Thanks for helping though man

[DjPantsSpecR]

well youre smart so i know you probabl sealed the connection as best as you could with minimum of e-tape.

So, if youre worried about blowing up, that wire would have to unwrap, and then short out on something. and then you might blow up.

so i cant help you, but i can try to give you piece of mind that it wont happen. mainly because it wont.

good fund too, we all knew it was fuel, jsut we couldnt help you exactly how. and i gotta laugh at the starter suggestion, especially on a car that is cranking fine.

[Z_Ro_01]

Ya the connection is sealedbut im still paranoid, lolbut as long as you "think" it wont happen my life is now calm, lol

all knew it was the fuel huhsureeehaha, probly true but just WERE the problem was, that was the problem.

And am I retarded or somethingtook me a damn half hour to figure out how to put the fuel pump back in...still isnt in right, lol, i gotta fix that

thanks for everything guys
