Engine Performance problem
1999 Ford F150 6 cyl Two Wheel Drive Automatic 225380 miles
My Service Engine Soon light came on and now my truck running bad. The problem is once I reach a speed of 20-35 mph the engine starts to running hard and seems as if it is missing and running ONLY on three too four cylinders. But once I reach and go beyond the above speed the truck or engine runs normal. After a few miles of continous driving it seems too reaches it normal temperature it will start running normal. I'm not sure what the problem is, but I need some help.
have the same problem?
