Hey guys i was wondering if any one can help me? I have a 92 hatch with 97 ls swap the car runs fine when the temprature outside is cool but when its hot the car would bog at 3k rpm and i can feel the lost of power. i've changed spark plugs spark plug wire and put a brand new dizzy in. No CEL when the car is bogging either checked timing and timing is in place. Any help would be greatful thanks in advance.
