[QUOTE="aaron97, post: 6388686, member: 66010"] Ever heard of high IAT's causing Lean conditions? We noticed the IAT is 138 degrees... and just for comparison (I know another cobra would have been better but..) we looked at the IAT's on his Audi A4 and it was only 102 degrees under the same conditions. The codes came back, but they only come up at idle when the engine is at normal operating temps. I don't know what the air temp was that day, but 138 sounds too high and he said it takes a long time while driving to get the temps to start coming down. Does anyone know what the normal IAT's should be? Like xx degrees above ambient air temps? That would be a good start. The stock air filter box and filter are from a '01 GT and the snorkel is removed, would that have anything to do with it? [/QUOTE]
