Well, I pulled off my air silencer on my 96 GTand put a K&N high flow on the stock intake, didnt even put in a full CAI. After doing it, the car gave me a lean engine code, and everytime I go above 4000 it puts the code back on and pulls a ton of timing, killingmy power. Is there anyway for me to get it to stop pulling this code short of a tune? (I have yet to hear it knock). I cant believe that just a high flow air filter could put my ratio off so bad to throw a code /grumble.

my only guess on that is that the k&n let some oil on the MAF making it read incorrectly. thats all i could think of, i know tons of people that have CAIs or just K&n Replacements and have none of these problems, im one of them. try cleaning your MAF with some sensor cleaner

+1 if that doesnt work this is the first case I've ever heard of where a k&n by itself made a car run lean.

+1...maybe your cars just so used to being choked from the non PI it dosnt know what its like to breath!!!!

Ill clean out the MAF senser and see if it helps... Ill just clean all the sensors and the IAC while im at it just to be sure. HOSS, Im hoping to help my car breathe and do a PI swap in the near future

also, make sure you didn't leave the clamp that's after the MAF loose
