rallyruss Posted June 27, 2006 Share Posted June 27, 2006 so my car is idling fine now and all but after adjusting everything my car is fackfiring alot...pretty much everytime rev up and let off and when im shifting gears. I am assuming i need to fool with the idle air screw...what should I do? my 85 did the same thing. it turned out to be the pulse air injection system. two marbles stuffed in the hoses fixed that problem. I guess there is a reed valve of some kind in there that does not seal properly and allows the fresh air to get sucked into the exhaust on decel causing a backfire.

SOOBOUTLAW Posted June 28, 2006 Share Posted June 28, 2006 My EGR valve gasket is a little leaky and makes it backfire when I shut the motor off. Freaks out the gas station attendants. Plus, cool four foot flame out the back. Link to comment Share on other sites More sharing options...

GeneralDisorder Posted June 28, 2006 Share Posted June 28, 2006 Exhaust leaks (in the y-pipe), or bad ASV. Fix the leaks and/or block the ASV's with quarters to prevent fresh oxygen from getting in. GD Link to comment Share on other sites More sharing options...
