Engine Performance problem
1995 Ford Taurus 6 cyl Front Wheel Drive Manual 147000 miles
SHO. 3.0L 6cyl MTX 147K. Engine runs for about 20 minutes. Gets up to operating temp. Then starts misfiring (speed up, slows down. Jerking the car around.) When it cools down, it stops. Just started happening a week ago. If I shut down while hot and try to start. It is hard to start (lights fade, hard to turn over. Like the battery is almost dead) then it turns over and misfires. If it is cool, runs perfect. It is definitely heat related. Coolant is fine, oil is fine. Battery is a year old and tested good. Could this be a thermostat, head gasket (no white smoke), alternator (alternator was replaced 3 years ago)?
have the same problem?
