its sputtering under load when i first hit the throttle it will lag for a second then finally stop backfiring and sputtering , then run fine all the way up the powerband, it doesnt do it for that long it does it for about 2 seconds , then it stops , but it happens every time i hit the damn throttle ... and i have a check engine light on that wont go off ... i cleaned the throttle body changed plugs wires , fuel filter oil change , a new distributer , and a new cap and rotor also , and a new o2 sensor on the header , and a new pcv valve ,you name it i have replaced it ... any ideas?
