BackFire
I put a new exhaust system (http://www.melroseheaders.com/produc...ystems/c-4.php) on my L98 1989. I have recently noticed some backfireing. I have had the system on for about 6-8weeks but the problem hasn't been noticable until 1 week ago. I would say it backfires frequencly but not constantly. could this be bad gas?(I use 93 but i had to put Pride... only thing around me at the time) Or am i looking at something more complex.

Backfiring is typically a timing issue. How's your electrical system? Tune it up lately?
Cap, rotor, wires?

It's an L98 with a distributor, maybe the distributor is lose?
Backfire is TYPICALLY an ignition related problem.
I'd tune the car up; cap, rotor, wires, plugs, coil, module
Then I'd set the timing.
If you haven't done it recently, may be time. I did mine a couple weeks ago. I have 32,000 miles.
