Engine Performance problem
1997 Ford Explorer 6 cyl Four Wheel Drive Automatic 94500 miles
Every four or five seconds, my 4L sohc will rev up about 100-150 rpms, whether im at idle in park or driving at speed. Its less noticable at speed but if you listen for it it can be noticed and there is a slight jerk. At idle, the small rev will actually overpower the brakes if they aren't pushed hard enough. This 100rpm jump only lasts about a second. Any thoughts? It happens all the time. Thanks.
have the same problem?
