ok so i've had my cobalt ss for 2 weeks now, and i bought an aem cai and installed it and then the cel came on. Now it seems that in second that car will not go untill about 3,000 rpms. It seems like the computer is cutting off the motor because i have it floored and u can just feel it lagging really bad. I have searched all over the place and i can not find anything that helps me out on this problem. Can someone people tell me how to fix the cel for the cia, or what could be wrong in second? I called dealerships and they claim gm has no fix for it. Can someone please help me, i'd hate to pay 200 bucks for something i can't even use.

 

Did u disconnect your battery? check all the connections? Go see what code you are throwing. just some suggestions

 

sounds like its in limp mode, disconnect battery, re adjust your new filter and piping and it should work itself out.

 

I did the disconnect the battery while I installed my Injen. Once I reconnected it, the cel came on like I had expected, but after 15 mins the car figured it out, cel went off hasnt come back on 2100kms. Try that route!

 

our engine bogs on the 1st to 2nd upshift pretty bad, are you sure its not that?

 

disconnesct the battery for about a minute. try n see if that works. if not check your piping and everything make sure the maf sensor is plugged back in. and for the cel i put in the ngk iridum plugs wen i did my cai no cel for it at all. 3400 miles..

 

I got put iridiums in mine also and my cel only comes back once in a while but doesnt stay on for too long.

 

my friend and i put an injen intake on his cobalt 2.4, and totaly forgot to disconnect the battery, he has not seen even the slightest flicker of a cel and its been a week since we installed it.
