I have a '77 Corvette Stingray whose engine misses and backfires. I've had timing reset, changed plugs, and verified there is no exhaust leak. I've also bought a new filter and carburetor. Any suggestions?
Bad plug wires (jumping spark) and a bad distributor cap are common to both misses and backfires. Other things you might want to check: vacuum leak, bad fuel injectors, and the carburetor accelerator pump.
