SamZman Posted March 29, 2002 Report Share Posted March 29, 2002 Backfiring will be caused by your car running rich. Is this a poping or an actual backfire? When does it occur? Maybe your 02 sensors are bad or not plugged in properly?... Quote Link to comment Share on other sites More sharing options...
Joe Posted March 29, 2002 Report Share Posted March 29, 2002 did you remove the cats? this will cause popping in the exhaust, as there is no flame arrestor, and lessened back pressure. Also, check timing. Quote Link to comment Share on other sites More sharing options...
Boost-n-Juice Posted March 29, 2002 Report Share Posted March 29, 2002 this is actually very common...it could be a lean pop also...is it a loud and violent back fire or just crackling? Do you have any leaks? Cool air can cause crackling. Do you have an adjustable fuel regulator? and or gauge? if you do then crank the fuel up a little bit, I personally think it's probably lean if anything, judging by your mods. Might want to check out the O2's - good luck! BC Quote Link to comment Share on other sites More sharing options...

DKilbourne Posted March 30, 2002 Report Share Posted March 30, 2002 Same thing happened to my friend. He put his h-pipe on and it had a large leak, needless to say he had it back fire when he was piping somebody and almost scared the shit out of them. So double check and make sure that it is properly tightened and go from there. Quote Link to comment Share on other sites More sharing options...

DKilbourne Posted March 30, 2002 Report Share Posted March 30, 2002 If I wasn't going out of town I might show you how it's done, but it can be done. Quote Link to comment Share on other sites More sharing options...
Guest 614Streets Posted March 30, 2002 Report Share Posted March 30, 2002 2 things , make sure your plugs are gapped properly , and more importantly advance the timing a degree or too. Quote Link to comment Share on other sites More sharing options...
Clifford Automotive Posted March 30, 2002 Report Share Posted March 30, 2002 seems like you dont have enough air coming through or too much gas now.... Quote Link to comment Share on other sites More sharing options...
