wow i just read over the posts, i can't believe NO ONE said timing :stoned: that's one of the leading causes improper idling... x.x

which made me wonder another question...

when was the last time it was worked on? timiing usually doesn't just go out on it's own... but even heavy jarring CAN move the distrubutor cap which plays a major role in timing (and timing is everything to an engine, improper timing can do everything from iradditc idling to rendering the engine completely useless unless adjusted back to it's proper setting)
