Hello i have done some searching and still have come up blank. i installed the CAI from AEM on a 06 2.2 cobalt. i have reset the computer twice now and after about 20 miles it still keeps comming on. please help. the wife is going to make me take it off till i can figure it out? can anyone help? heres what i have done.... unplugged neg battery cable installed CAI and drove nicely for 5 miles then got on it no light. next day drove to 7-11 and CEL came on... went home neg battery cable off turned start key waited 22 min reconnected battery started car let it run on it's own for 6 min then drove it 15 miles then CEl again... in walmart parking lot un plugged battery turned key waited 45 min shopping then reconnected battery then started it for 6 min again on way home about 15 miles still light came on what gives??

Mines comes on but no where near that frequently! I dunno man, maybe you have a leak somewhere? BTW mines a 05 SS S/C and it's only came on twice in the 6000 or so miles I've put on it since then.

I'm not sure about Cobalt 2.2 technicial specifications, but did they have a mass air flow sensor somewhere into the intake? If yes, that's the most common problem when installing a CAI. This sensor is VERY VERY VERY fragile and maybe you damage it during installation or with the CAI installed it doesn't take a great measurement of air coming throught the intake and give the ECU an error.

If the Cobalt don't have a MAF sensor... I'm confused cause you must have a sensor somewhere to tell the ECU to light the CEL on!

yes it's the maf. i hope someone cracks the comp in this car soon

did you clean all the oil of the filter before the install? Did you put the maf in backwards? Is everything connected back up? Just check the easiest stuff first. You can goto autozone or pep boys an get the code scanned so you can see whats complaining. That would help pin point it.

well it's been removed. i looked over everything and it just dosent work. the maf only goes in one way. all the connections are tight. still the light comes on. i called AEM and another performance shop and they both said there is nothing i can do. "just drive it it dosen't hurt it." well that just dosent fly i'm not mad just sad i figured for $200 bucks it would work.
