OK - Mechanic is stumped. any ideas??

[Mustangs_Suck]

**** **** ****...it's already starting to act up. 3-4000 Rpm's there is a huge stuttering..

My brakes are shot too lol, They constantly squeal now when I drive it.

Brakes are no prob, I've done em before on my last 240sx, it's just this stuttering ****..I guess I'll look at the IC piping to see if it's starting to come loose already again..if not. I'm gonna be lost again.

sometimes if there is a stuttering only at certain RPMs, or a certain part of throttle, it could mean your TPS is going bad, but I would get some backup on that before you start replacing parts.

[Mustangs_Suck]

hmm, it might be my tuning. 3-4000 rpm's are held back alot, and it opens up around 4500 rpm's again.

When I shift it'll "pop" out the muffler at times.

Spark blow out? I could of fouled up my plugs from this tune I set it to..

chris my stuttering before was caused by not taking off the EGR. at those rpm's it would just pop lean and have a huge JUG. i dont know whether you took off your EGR yet but if you didnt you should. if you did alredy, then hope someone else can help you.

[Mustangs_Suck]

Hmm I can't remember if that's taken off or not.....mechanic mentioned something about it, but I don't know if he said he got working, or if it was missing.

I'll take a look at the service manual, and poke around to see if ti's there.

thanks

that sounds just like my friends (s13frsh13) he had a sputtering prob just around there and it ended up just being spark plug wires.. hope all that it is for you. good luck

[JDMEnthused]

ugh.. this reminds me of how bad i need a tune up

[Chezedik]

check MAF. I didn't read 6 pages of posts, and I didn't need to. You are in Limp Home mode, and the easiest bet would be the MAF. Have fun.

[Mustangs_Suck]

heh, cars been fixed since then...well at least sort of.

Have a stuttering from 3-4k now, and I'll be re-tuning it, checking to see if the EGR valve is on, and if it is, take it off, and also looking at my IC piping this weekend.

I shook the piping today and the part that popped off last time, seems to be more loose than the other side again, so I think it's starting to come undone again...I need it welded.

[Craving4Boost]

i dont know....loose charge pipe wouldnt cause stuttering at those rpm's. just take a quick look under the 4th runner and see if the EGR is there. i have a good feelings its the EGR

2 quickies for ya....

1. The SAFC is probably displaying max values... just push down or something. I don't quite remember but it's in the manual.

2. GET IT TUNED!!! Do you have a WB02? Wouldn't wanna blow it now that you have it back and it survive the last one, would you?

I re-tuned to the specs of one of the threads on here that was called "SAFC settings" or something of the like...car is running better now...no stuttering, I just feel like it's being held back...probably a vacuum leak or something..exactly what it feels like.

Thanks for the tip on the SAFC, i pressed down, and it went back to monitoring one thing less I have to worry about.

I'd get it tuned, but it's gonna be going into storage in about a month..no need to drive it 60 miles north, spend a hundred bucks, and drive it back for only a few weeks of usage. She seems to be greatly tuned now, I just need to find the source of my intake leak..which I bet is my damn intercooler piping. Haven't had much time to look at it yet, due to daylight savings time it gets dark as **** at around 5pm here now heh, with school and whatnot, doesn't give me much daylight hours that I can poke around at the car.

oh well...it seems like it'll last me until I put it away..that's all I ask of it right now

[huguetpj]

Since you have no idea what the tuning is right now I would drive the 60miles pay the $100 (which you still are going to have to fork out after winter anyway) and just have peace of mind for a couple of weeks. Are you sure it's a leak? If it's bad tuning you might be killing it slowly.

Just a word of caution from someone who has killed 3 motors from not "listening" to them

[Craving4Boost]

chris did you check the EGR yet

[Mustangs_Suck]

chris did you check the EGR yet

Checked tonight...didn't see anything that would resemble it, but didn't have much light to see it.

Putting my rotors/pads on tomorrow, so I'll check again...

[Mustangs_Suck]

Well I just searched around on it, and it doesn't sound like removing the EGR is just as simple as popping it off and being done.

I have to cut out a plate of sheet metal and drill it into the intake mani to block it off? screw that.

[huguetpj]

It's not that hard. Just remove it, cut out a piece of sheet metal to the necessary size, then drill it to screw it into the place where the EGR use to be screw into.

Or you might wanna try the quarter approach.. putting a quarter between the EGR and the intake mani.

[Mustangs_Suck]

Well i did alot of work on it yesterday. brake rotors and pads all around. tightened my suspension, vacuumed out the whole car, wiped the whole trunk and wheel well areas with soap and a rag, got alot of mud and crap off. put back seat back in, rear view mirror back on. doing well. just have to take care of my seat belt, and fix a few broken lightbulbs and i'm pretty much done with everything.

As for the EGR. I'll probably wait until after winter to d!ck with that thing...it drives fine now, just a bit of stuttering. It only happens when the car warms up though, when the motor is still cold it's faster than all hell.

take off the EGR completley. youll have to take half of it off first. and then you remove the bolt whihc holds the brake booster line in place. then unbolt the whole egr from the intake manifold. once thats off, there will be a gasket. take that gasket and use it to drill your holes on the sheet metal. after that put the sheet metal on and use the gasket. if the gasket is too jacked up like mines was....put some rtv sealant..works fine because theres no heat

thank's for the how to I'll get it done sometime this winter I assume while it's in storage.
