Chevy Astro Van, 1992, V6 4.3L (not Vortec) 299,000 miles don't laugh. (one owner)
The Van does not burn any oil, oil pressure is real good. All cylinders are within tolerances for compression. The thing died one day without any complications noted (May 07). towed to garage and it started up without problems. fuel pressure down, R/R fuel pump and filter. Still was having same problems, R/R the distributer also, still problem. R/R plugs, wires and distributor cap and roter, still having problems. R/R the a/c (it just stopped). Sunday Nov 4th it was still missing or cutting out and i stopped at a traffic light and it died. came back 26 hours later and it cranked without problems, still hesitates. you can be on flat surface, downhill or uphill, idleing and it will hesitate. Not all of the time.
seems to run better at lower outside temps (below 50) than higher. any ideas except replace the engine because it feels to me to be something else. I do not think replaceing the engine will solve the problem?
