Engine Mechanical problem
2003 Ford Explorer 4 cyl Four Wheel Drive Automatic 110000 miles
After my car is warm, whether in Drive or 3rd gear (doesn't seem to happen in 1st or 2nd), when I take my foot off the accelerator, there is a jerking and thumping. More noticeable after changing spark plugs at last checkup but has been happening for 1-2 yrs, much more now. Passenger noticed jerking too. Counted 20 thumps in 10 secs going 60 mph and noticed 10 thumps in 10 sec going 30 mph in 3rd gear (going down hill).
Mechanics couldn't find anything the first time.
have the same problem?
