Car is backfiring... Why??
Car is backfiring... Why?? Got a 2002 camaro SS with 23,000 miles, installed BBK long tube headers, dyno tuned, lid, AIR/EGR delete... That was about 4 months ago, been starting to notice the car backfires when I first start it, doesn't do it all the time just when it wants! And I'll turn off and start again and it won't back fire. And it will do it on cold or warm start. Does not backfire when driving. I also have new plugs also.
Did it start doing it after you changed the spark plugs, or was it doing it before..?
Have you checked all the coil connectors, to include the spark plug wires for a loose connection..?
How's you fuel mileage been since this started, any noticeable decrease if mpg...?
Can you cause it to happen by wiggling the coil wires and plug cables around..?
Have you had it scanned for codes..?

Haven't checked the plugs to see if any are loose, I'll do that this weekend. As far as gas mileage maybe a slight decrease. And yes I deleted the AIR when I did the dyno so the PCM reads it as nOt being there.
