Squirrely problem with #5

[BigBlocksRule]

1996 Vortec had a miss on #5. Plenty of fire and compression, every time I pulled the plug it was wet. Truck ran fine for a few seconds right after it was fired up cold, then it would start to miss again. Once it had been running, #5 would continue to miss, even on a restart.

Fuel pressure regulator was leaking into the intake, actually had a good bit coming out of the regulator discharge. It was hitting the intake on the edge of #5 runner, so about half of the leak was going into that cylinder. Replaced the regulator and she runs like a top.

Apparently there was enough fuel to flood the cylinder and once the plug got wet, that's all she wrote.

Pain in the butt but a cheap fix.
