GMC 1500 Suburban 4x4 mystery problem
My 1999 Sub has been a great ride and until recently never let me down.
Here's the problem. After about 2 hours on the highway, the engine shuts off. I can get it started again, but it will misfire and then shut off again. If I let it sit for an hour or so, its good for another 2 hours before it does the same thing again. The symptoms remind me of a truck I had once that suffered from a ba coil, but I don't even know if this engine has a coil' I can't find one on this engine. Any suggestions? Thanks!!!! |
