MY 1988 CHEVY K1500 PICKUP IS BACKFIRING THROUGH THE LEFT BANK ON THE THROTTLE BODY. THE THINGS LEEDING TO THIS PROBLEM STARTED WHEN I FOUND OUT THE HEAD WAS CRACKED. I REPLACED THE HEADS. I PUT EVERYTHING BACK TOGETHER STARTED IT UP , IT RAN ROUGH AT IDLE UNTIL I ADJUSTED THE TIMING. NOW IT IDLES FINE BUT WHEN YOU STEP ON THE GAS IT BACKFIRES. I TESTED ALL THE COMPONENTS ASSOCIATED WITH THE ENGINE ELECTRICAL AND THEY ALL TEST GOOD. IS THERE SOMETHING IM MISSING OR MAYBE THE TIMING IS STILL OFF. IM CONFUSED ABOUT WHAT THE PROBLEM COULD BE. PLEASE HELP

So far it sounds like one or more valves are too tight. Just how did you preset the adjustment? What engine?
