uber stressed

[sjbsuperman1425]

well my car ran fine this morning, still doing the idle hunt and running a bit rich, so i said, well lets clean the MAF at school. i cleaned it, reinstalled it and bam, runs like snot!

it will idle but barely a 700rpms..i can rev it but wont rev past like 5k or so. left MAF unplugged to get home and wouldn't rev past 2k like usual. did cleaning the MAF (w/ MAF cleaner) mess it up? it was throwing Code 12 in Mode three..i got home, unhooked the battery for just a second or two, hooked it back up, and did mode III again and got code 55 but it still ran the same..im sure the plugs are ruined..is my MAF junk you think?

if anyone has an extra CA MAF, can you help me out? i really just need a car to drive to school thanks..

[slideordie85]

i will have one in a couple of days. i am putting my z32 on.

[Ca_Silvia]

I replied in your 240/gen thread but, i'm putting money on vac leak.

I have a ca maf for sale, known to work 100% i can sell it to you if interested.

[sjbsuperman1425]

how much would you guys want for JUST THE SENSOR, not the whole assembly shipped to 48708? im really low on cash...

as for the boost/vac leak. thats exactly what it acts like. except on initial start up, its at 1500rpms or so and then idles down to 700rpm and is sh1tty, but if i tap the gas it will go back up to 1500 and be good. as said before, unplugging MAF helps BIG time.

btw, MAF code is now present.

[Ca_Silvia]

I paid 80 for mine, i will let her go for 50+shipping. LMK

[sjbsuperman1425]

fair price, think you can hold it for me for a few days incase anybody decides to jump on it? anybody else have a price?

i really find it hard to believe that me cleaning it messed it up, but its possibly i guess..im unhooking the battery tonight and resetting the ECU so maybe it just has to recalibrate or something..anything else guys?

[Ca_Silvia]

I'll hold it no problem, one guy already backed out so...

FYI when my 1st CA MAF went out, it was a little dodgy then i cleaned it and bam! Did work at all after that.

[sjbsuperman1425]

you mean you cleaned it then it DIDN'T work at all, or it worked good?

Your cleaner put a film on the maf's hotwire which prohibiting it from getting a good reading. In the future, if you guys are going to clean your maf's hotwire, may I suggest 90% isopropyl alcohol as your solvent.

Dee

[sjbsuperman1425]

so is the sensor junk now, or can i still clean it? where do i get isopropyl alcohol?

[sjbsuperman1425]

ok well i found some 70% isopropyl alcohol in my bathroom..this and a Q-Tip should take the "film" off the wires correct?

[exacyzm]

I would be wary of 70% isopropyl, the other 30% could easily leave a film on the hot wire also.

I use 99.98% isopropyl for cleaning purposes and it dries with absolutely no residue.

Use the most pure isopropyl you can purchase.

[Ca_Silvia]

you mean you cleaned it then it DIDN'T work at all, or it worked good?

Its was intermittantly working, then i cleaned it, then it stopped working completly

[sjbsuperman1425]

im guessing i either shorted out the sensor or just have a film/residue left on it..if it was shorted out, wouldn't the ECU go right into limp mode? the running rich and idling rough would be the system reading to much air and that would mean the MAF would have to be reading something correct? then since unplugging the MAF helps and then the system is NOT reading anything, it goes to limp.

So im thinking the sensor itself is ok, and it just has a film obstructing/skewing the readings of the sensor. (im just trying to digest what Dee was saying)

im going to try some CRC Electrical Contact cleaner first (had luck with it before) then if that doesnt' work, i'll try the 99.98% alcohol (get at Walmart?)

[sjbsuperman1425]

From Progman in Running rich? thread:How did you clean the MAF sensor? It should have worked after you reinstalled it. no reason for it not to. I have plugged and unplugged a MAF on a running CA many times before. Perhaps its was problematic and it finally died?

i dont see any reason for the MAF to not be working. it idles like snot with it plugged it, but once i get going, it will boost at 3k and drive ok, but EXTREMELY rich. i forgot to mention this. so its sign enough for me to believe it is WORKING, but is just sending the wrong signal. Maybe this can be tied into what Dee had said? im going to clean it with Isopropyl Alcohol but dont know where to get it in the 90% range..all i can find is 70%..what do you guys think after this added information

in my eyes, i feel the MAF is still good, just there is something skewing the readings.

[MeanGreenS13]

i think you my friend may have worse luck with the CA than i do... wow

[sjbsuperman1425]

i think you my friend may have worse luck with the CA than i do... wow

no kidding..idk im 90% sure the MAF isn't funked as i could drive it and it'd just run super rich, and i think only threw a code because i unhooked it sometimes..im going to go home today and reset the ECU, as leaving it the battery unhooked didn't work..then let it idle (as crappy as it does) and see if i get the MAF code.

If it was truly bad, you'll get the "12" on your ecu. Other than that, becareful when cleaning it with a Qtip because too much pressure and you will break the wire and then you're screwed.

i have gotten code 12 before, but i was unplugging the MAF and not resetting the ECU during this time.

MAF plugged in = rough drive until 3k or so and runs +++rich (idk about code 12)MAF unplugged = smooth idle, code 12, can't rev past 2100rpm

[sjbsuperman1425]

two more things:

1) i removed the emissions canister and the hose going to the fuel tank is open..should i plug it?

2) if i figure this out, i am going to divide up the change in my paypal account and everyone in this thread will recieve a cut lol

[Ca_Silvia]

1-yes leave open

2- i only take payments larger then 20.00

[sjbsuperman1425]

put ignition to on, code 55 in mode III, turned car on, idle at 1500, code 12 present. would a film on the wire cause an abnormally high voltage? i dont understand how using MAF cleaner would mess up my whole shiz..

Did you check the circuitry on your AFM's connector or the harness's connector? Your AFM could be very well be damaged if it's giving you a code 12.

With your ignition on and your AFM all connected with the engine harness, test the voltage on your white wire to see where it's at with the engine not running. If the voltage is .8 volts or higher, go find a new AFM.If your reading is .5 volts, blow into the AFM while monitoring your voltage reading. If it doesn't get any higher than 4.0 volts or it goes higher than 5.0 volts, go find a new AFM. Anything else, get back to us with the results and we'll take it from there. your problem is a simple fix a most are, but to the knuckleheads that don't listen, I wish nothing but the best and hope they eventually solve their dilemmas.

Dee

[sjbsuperman1425]

i planned on doing this, i just dont know which wire is the white wire, and how do i do that with it connected to the harness? i do have to strip away the sleeves on the wires?

[sjbsuperman1425]

well everybody, im thinking the MAF is dead cleared codes, and the code 12 came back right away. the electrical cleaner left a residue on my hand today, so i did the 91% alcohol which did NOT leave a residue. still...nothing! i didn't check the voltages as you said dee, but i know that the harness is good. looks like its time to buy a used one..

another thing though, that cap on the MAF, what is it for? i know if you take it off there is a spot to use a flathead screwdriver, but what does it do? just wondering about it.

It's dead, dude! I have an extra AFM somewhere in the garage, but let's see if someone can help you fist. If they can't, I'll let you have one for some gas money or something like that. Some things I can let go for the low-low, but some have to be treated like GEMS and I have to charge according to scarcity because once I get rid of something, there's no telling if I'll ever have a hard time finding that part for myself.

[sjbsuperman1425]

i hear ya Dee..its hard enough tracking stuff down when you need it..if you want, my e-mail is [email protected] have a myspace friend that has a friend that owes him a few favors and might pull some strings for me but idk. maybe just e-mail me a price tomorrow around 5pm or so? im going to need one for next week..

[sjbsuperman1425]

ok well that fell through..wanted like $100 for it..

Dee wanna e-mail me a price? theres someone on Zilvia with one also, but i cannot get ahold of him.

[Ca_Silvia]

I paid 80 for mine, i will let her go for 50+shipping. LMK

[sjbsuperman1425]

i have one from a guy on Zilvia for $55 shipped priority. can you beat it? lol its just like ebay or something, but in reverse
