My '94 F150 runs fine until driven about 20 miles, then stalls and dies.?
When I try to crank it back up, the engine doesn't want to turn over until it sits for about a minute. While driving down the road it seems fine, although I do get some valve chatter upon heavy acceleration. Also seems to be using way too much gas. I have changed the PCV valve, had the timing adjusted, tried high octane gas and fuel treatments, changed the fuel filter..... Nothing helping so far. The truck did sit up for a couple of years before I bought it. Any Ideas?
