![]() hey i have a 90 gt and it has been backfiring out of the intake since i bought it. It only dose it in the morning or when it is cold but when it heats up it stops. I have tried adjusting the timing and cleaned the MAF, put a new IAC on and it will stall in the morning and when you start to go the pedal will go down but nothign happens then it backfires and the car will take off.........any ideas????

![]() Usually an intake backfire indicates a lean condition and an exhaust backfire point to being too rich. Waht is initial set at?
