idk maybe its nothing, but my gt use to make this huge suction noise every time i turn off the car and now pretty recently it hasnt done that and my rpm needle is jumping around a little more...i took off and put back on and took off and put back on the intake to make sure that isnt the problem, still same result, the things i have done most recent are the hvtb and painted my ignition coils, but i know i put them all back on right and made sure no paint got under them...anyone know?
