The truck began to run rough and misfire. I set the timing with a light at 12* BTDC which made the engine run much smoother but the distributor is popping. It is loud and is not a rhythmic sound. I have checked the firing order of the plug wires and it was good. Spark plugs look good. I disconnected each plug wire from the distributor individually while engine was running to check if all cylinders were getting spark. Each cylinder was getting a spark since the rpms decreased with each wire disconnection. I replaced the distributor with a new one since it was original but the distributor is still popping. What is causing this popping (or misfire) from the distributor? Could it be faulty plug wires?
have the same problem?
