OK thanks, Ya I thought it might be the tornado thing but I didn't know if the fuel sensor in the enigine was that touchy. I checked for other threads about installing after market intakes and there was no mention of throwing a code. and the OnStar guy said it was a sensor in the engine. because I even asked him about the gas cap. I guess the tornado thing does work if it throws codes like it is doing. Too much air? never heard of that in a engine but I am going to take it off later tonight. Thanks for the help
.
since I do want some sort-of air filter upgrade any recamendations??
