backfiring during idle
backfiring during idle So I put in a new cam and before the car was having issues with a mis. After the cam swap while its idling it backfires and pops? Would anyone think its the opti spark? the wires are virtually new!
Hate to say it, sounds like an Opti. Unless it's something goofy like a coil, but chances are you'll be needing to dig into the front of your motor again. Upgrade to an MSD setup, seal it up good and dont worry about it again.

well plug wires are all on correct checked that coil is good also I mean it was missing before the cam install anyways and i thought it was ust plug wires so i went back with the same opti but it was missing exactly like it was before i put the cam in it
or most likely a plug wire mixed up...seen it a million times
you are probably right I will recheck them tonight but then I have a miss when im just driving also in conjuction to that and before i changed the wires it didnt backfire... so i guess i did put one on the wrong opti post. but I have a horrible miss when i give it any it a little throttle or alot it doesn't matter so I'm thinking that might be the opti also because the coil is new and the wires are new
man recheck them...then stop do it again...then do it once more...then have a friend do it...im telling you we ALL have mixed them up i actually had a guy take his car to 3 differant chops that couldent figure it out id idles fine but above 1000rpm it backfired...i thought that was the problem...i looked over them 3 times figured it out on the 3rd time looking over them
Joe Overton came down to tune my car back in the day and I had installed the plug wires on the opti. I assured him that I had it right. So he tuned and tuned and tuned and couldn't get rid of this backfire.... So he wrapped it up for the night and told me that he would brainstorm and think of what it might be. I again assured him i had all the plug wires correct cause during the tune he asked me like 5 times if i was sure... Sure enough my buddy comes over and takes a look and he's like "dude #2 and #4 are crossed at the opti".... I was embarrassed to say the least and I called joe and we laughed about it... I uncrossed the wires and the motor picked up like 100hp no lie.....
I'm going to check them but we drove it earlier that day and it had a miss in it bad. so I changed to the new wires and thats when it started backfiring im sure your right im sure i got them crossed up somewhere but the thing is even if they are crossed it should still fire up which it doesn't want to do and when it does it will idle for maybe a minute and backfire and then die.... I had it tuned yesterday but even if they are crossed up it should still idle ya know
