Has anyone had any problems with an AEM cold air intake in their car? I put one in and my check engline came on because if says it is running lean. Does anyone have any solutions besides disconnecting the battery?

Bro you are going to have that CEL until you get a reflash from a chevy dealer. The whole battery fix is a bunch of crap. It fixes it for a day or 2 and then the cel is back. Go to any chevy dealership and tell them you need a reflash or just buy stage 1 or stage 2, they come with a reflash. :twothumbs

Well I have a chevy cobalt LS 2005 2.2L. I went to the dealer when I got my car inspected and they said it was running lean. I had my car back at the shop today for my car hesitating and they said they can't do anything until I put my old air box back on. they scanned it and the same 2 codes got thrown from the computer. I think there could be a problem with the mass air flow censor but I don't know.

Sorry I didn't know you had the 2.2 You should click on the search button and type in 2.2 AEM intakes and you should find more stuff.

get rid of it i had the same problem. aem can't help, gm can't help. the weapon r is a short ram and mine felt the same. NO CEL

What brand is good. I have a cobalt 06 LS cpe, and I'm new to this.

i have an aem intake on my 2.2.. and the cel light will eventually phase out.. mine has been off for over 1000 miles now and the last time it turned out it was on for 12 miles.. the car will eventually remap itself for a enw fuel pattern

Mine was on for about 2 months. It went out twice for about 1 day each time. I changed the filter and the light went away for 2 weeks but just kicked back on yesterday. I might just go with another intake or put my stock airbox back in.

all u hav to do is get bigger injecters i had the same problem
