My engine is running rough and the engine light is on. I repaced the spark plugs and plug wires about 2 months ago. It ran fine for a cou;le of weeks and then the plugs started to fowl. I replace the plugs again and the engine ran fine until yesterday. The idle is rough and the engine light is on. Sometimes the engine light blinks on and off while excellerating.

I think the pluga are fowled again. I removed one plug wire at a time from the distributor to isolate each cylinder. It does not appear to be just one plug failng.

Any sugestions

First, what type fouling is happening? Oil, fuel, burnt tips? what? The second thing is read the codes, the truck may be telling you where to start. Autozone reads codes for free, post all codes here.
