Backfires......
I'm working on my brothers '90 Iroc, trying to fix the backfiring problem it has. It backfires during deceleration through the exhaust @ like 3,000 rpm and higher. Any ideas @ what the problem can be? Any suggestions? I've already checked the timing, valves, timing chain,(all were good) and are in need of help. Thanks....

All the plug wires are good, and they're on the right plugs?
Perhaps one of the injectors is bad? Do an ohms test on each injector. They should be greater than 12 ohms, preferably 16 ohms.
