My dad has a 1988 toyota pickup truck that backfires when the engine is started and revved at a stand still; it will eventually cause the engine to stall.

Could be valves ... how many miles?


I'm leaning towards a fuel delivery problem. It's flooding out the engine after running a bit. The residue in the cylinders is causing the backfiring when it's started. I don't think it's a dying ECM causing timing problems although that's an option. I'd be curious if there's gas in the oil pan.
