Hello, I'm having problems with my 1989 Chevy Silverado 1500. This truck has 112,000 miles and I have kept it well maintained, but it dies while you're driving down the road. It has a propane system that I installed, but the problem occurs while running on gasoline or propane: the "service engine soon" light comes on, the engine starts running rough, like "dieseling", and a few minutes later the truck will die. If you pull over and shut it off until the engine is cool you can get back on the road and it's fine. It only has this problem once in awhile, not all the time, and I have checked and changed every filter, valve, and line I can think of. Computer codes didn't help, and I've been to 3 mechanics. The truck does burn a bit if oil in the exhaust when you fist start it, and the heat gauge reads at 210 degrees when it has trouble, which is a bit higher then normal even with plenty of coolant. Someone suggested to check a exhaust valve, or the distributor/ignition module. Any ideas?
have the same problem?
