Question

69 Camaro with a 350 and HEI distributor. Car has begun backfiring randomly through the exhaust pipes, even at an idle. It also seems to speed up and slow down on its own at an idle. This has cropped up in the last few days. Is this a distributor problem with the advance or something? I have no idea how old the distributor is or if it has ever had any attention.

oh man, vacuum leak,timing chain,valve adjustment,cap and rotor, plug's, plug wire's...........

where are you at? do you have cold wet weather? if so check for a damp dist. cap.

also check for vacuum leak's just for something to do under the hood.

it could be lot's of stuff a lean A/F can cause this too.

I just went through the exact problem your having. I would change out the plugs and wires first. Maybe even the fuel filter. If that doesn't fix your problem, then focus on the distributor.

It may just be water in the fuel...we have been having big problems with that around here since it got cold...enough water in there will definately make it backfire.
