CAI = stalling

Bassbreaker · 11-03-2008, 07:35 AM

I set up my new Ebay CAI and when I went to start the car, it stalled twice. I don't understand what the problem could be.

I never however cut the air box to allow for the plug connecting into the airbox to be attached. it is plugged in but the part with the little resistor on it is just hanging outside the filter. Could this have anything to do with the stalling? It won't stay started for more than 2 seconds. The maf sensor is connected, all hoses ae attached as well as the vaccum hose.

What could it be?? Could someone post pics of theirs?

Mine is a 95 GLE so if anyone else has one with a CAI it would be great..

Unplug your maf harness, then see if the car runs. if it does, you most likely have a bad maf.

The maf(especially an old maf) can be fragile, sometimes just bumping a old/orginal maf around a little will kill them.

just try it, shouldn't take a minute of your time.

do you mean just unplug the plug itself? Or take out the maf sensor and run a straight pipe line from the TB to the intake

Just the maf harness, leave the maf sensor itself in place. the ecu will go into "limp home" mode and run a default setting for the maf. the engine will not rev over 2500rpm or somewhere around that # with the maf unplugged.

lol..you were right man...unplugged the maf plug itself and she stayed goin...plugged it back in when it was still going and it stalled...thanks for the help

Well, the car stalling when you plug the maf harness back in while the car is running is normal, even a maxima with a good maf will stall when it is plugged back in while the engine is running.

But the fact that it runs fine without it plugged in is the determining factor of a bad maf.

I see...thanks for your help tho...I do have another max for parts so I hope that MAF is still in good shape...I was pretty careful with the one I took out, it didn't take a hard knock, must be pretty fragile...it's actually fairly new too

What do I do about the plug that was originally attached to the air filter box? There is no box there now so the end of the plug is just hanging there. What does that do? Is it an O2 sensor? Is it needed? Can I just unplug it and get rid of it?

Feldman · 11-03-2008, 03:29 PM

i think the plug you are talking about is an air temperature sensor. I would relocate it somewhere that it can get some fresh, cold air so i can get a reasonably close reading

Question for anyone....if you unplug the MAF harness...it still runs, but is it safe for the car to run without it? Like can I drive the car for a bit with it unplugged....it being in the "Limp home" mode like I was told

yeah, you can run it for as long as you want, it's not going to hurt the engine.But you won't have any power above 2500rpm, the engine will fall flat on it's face.

probably broke and waiting until payday dude

I've been there plenty of times.

lol...right on the money...they are like $250...i'm not looking for power..just to get it somewhere if need be...as longas I canthen it's a piece of mind

i don't want to sound like a smart ass but...have you put you maf in correctly? meaning with the arrow (flow) pointng towards the tb? i wouldn't have asked but sometimes the simple things that are missed cause problems - i knocked my maf down twice putting on the intake and no probs.

I might have thought that was it, but I don't even need to look at it a second time cause the plug side of the MAF is on the same side it was...the plug wouldn't even reach over if it was on the wrong side.

I didn't knock the MAF around or anything...I can't see it damaged or anything...but when I unplugged it it worked...plugged it back in...stalled

you wanted pics of a cai setup. http://s254.photobucket.com/albums/h...xima/?start=20

those are before final tweaks but a general idea. i have the same year/model as you and had no probs. have you checked for codes? maybe a ecu reset will help?

I hope you have your valve cover reconnected and no longer an open port on the intake after the MAF like shown in those pictures.

the vc has a breather on it so i don't get oil fumes in the motor, i'm guessing you're talking about this fitting that's capped off?

not to sure what you mean....I don't have an adaptor piece like the one he has to replace where it went into the air box. Kinda confusing I know but its the other plug next to the Maf plug...once the air box comes out, then there isn't anywhere to put the resistor end of that plug (AIT)? My set up is a little different than his..i'll try to get some pics

i bought mine off ebay too. our iat is not a plug type like 4.5 gen so i made holes for it in one of the couplers and put it there.
