My Truck is Running Rough :(
 

I've got a 1970 Chevy C10 with a 350. I was on my way from VA Tech to Lynchburg and after a few stoplights on 460 I realized that during acceleration my truck was running rough. I eventually pulled over into a gas station and unplugged all of the spark plug wires to make sure that they were securely fastened. That worked for a few miles, but then it started up again. Any Ideas? I recently changed the spark plugs and they were not corroded at all other than normal wear and tear.

Thanks,

Eric

plugs gapped right? wires look ok?

Yeah the plugs are gapped correctly and the wires were loose some time ago but that was fixed, but I did double check them and they were on all the way...I'm stumped. :(

Check the contacts under the distributor cap. They might need to be cleaned.

my truck was doing the same thing, it was the spark plug wires arcing(grounding) on various metal brackets. its a cheap thing to eliminate. give it a shot. gl

I was gonna say the same thing, sounds like you have a wire grounding against a piece of exhaust. Easy to just wait till dark, pop the hood open, and look for blue arcing.
