Yeah I already thought about that and I am on the breaking point of doing that. If this problem dosen't get fixed soon I will put my old stock airbox back in.

on any car that i worked on with a MAF and a CAI i've gotten an CEL. what usually helps if grabbing a $40 code reader from pepboys and letting it tell you the code, usually, it's the lean code which you all read. as i understand it, the car will toss up a lean code if any of a number of sensors are outside of "normal" the car WILL adjust itself to a point, but there is a limit to that point. the nice part about the code reader is that it will allow you to clear the codes without disconnecting the battery, which is honestly not a 100% sure method of doing it.

After I got the CEL.. I disconnected the battery twice. With about a weeks worth of driving in between. After the exhaust I got the cel, disco the batter. It still came on so I drove about a week(about 500 miles worth of driving for work)and disco just the NEGATIVE terminal (not sure if it matters) and it went out ever since. Almost a week now wooow

Josh

I have already had the code cleared but my light came back on. I disconnected the negative terminal on saturday and my light oppped up afer about 10 miles of driving between saturday and sunday. I have a another call into aem and they still havn't called me back yet. I am just looking for any suggestion I can get right now.

i have had an injen cai on my car for months and the light never came on. aem just makes crap products thats how its always been.

shoulda gotten the injen

...if Injen doesnt throw a CEL and the AEM does doesnt that mean the AEM lets more air flow then Injen does?

i don't think so. lets try being logical... the OEM MAF would most logically be built to be able to measure the amout of air that the STOCK 2.2 could ever injest at any of it's STOCK RPM range. that is to say, it would only make sense to make an MAF where it didn't matter if the throttle body was just in open air, it would measure enough. with all that, it seems to me that the volume may not be the issue, it could be other factors. for example

bad placement of the sensor in the tube makes the air swirl around it funny so that the car thinks that there is not as much air as there really is... not enough fuel and then VIOLA the O^2 sensor trips the alarm.

wrong size pipe sucks air at too high a speed and it does it the same way.

damage to the MAF when people install it

not allowing the car to adjust itself. with any modern ECU car, i'd say after you get your new part in, let it idle for about 25 minutes before you hammer on it so that it can keep it all within spec.

I jsut got my car checked out and it is still running lean. I was told to get a diagnostics run on it to check for leaks or if it is a bad MAF censor. I just got off of the phone with aem and they are trying to replicate the problem and they will call me back when something happens. Until then my car is running lean and I will have to pay $80 an hour to get a mechanic to look at my car.

Josh

I got the problem figured out. It is the air filter that is making the cell come on. I took my car to the dealer and had a diagnostics ran on it. Everything is good except the told me the filter is letting too much air in which is causing the car to run lean. They told me to replace the filter and that is what I am going to try. They gave me a part from summit to try. But they said if this dosen't fix the problem then they said I have to put my stock air box back in. Let's hope this isn't the case!

anyone find an individual throttle body for the 2.2L

hay guys i am new to this hole 4cl sceen. i am used two my big block chevy that runs mid 8s in the 1/4. i just got an o6 ls 5speed i have plans of putting a turbo on it but dont have the money right now, could anyone help me with some small mods for some small dollors thanks mark

I just got cobalt ss and you saying a injen works pretty good.

I had my AEM cold air instake in for about 3 months, and during the time I'd say the light came on probably 5 times out of the month. They said it was a lean code but I guess the car needs to just adjust to the changes..So I ain't stressing it much.

abcrazy

so if i get the AEM CAI will i have to do anythkng. i dont really understand the whole thing. it seems like sensors are to senstive for it. PM me with details
