Engine Mechanical problem
1999 Mercury Tracer 4 cyl Front Wheel Drive Automatic 180, 00 miles
My engine quit, I looked at the timing belt and it appears fine. However the number 3 spark plug gap was touching the electrode, the number 4 spark plug was crushed into the electrode. I think the cam shaft sproket may have sliped as my timing marks don't line up. Even after I re align the timing marks the engine won't start, I have a spark. Is it possible for the timing belt to stretch, or slip over some of the teeth.
