2001 Jaguar S-Type Repair Question
2001 Jaguar S-Type 2001 Jaguar S Type hesitates
2001 Jaguar S-Type 6 cyl Two Wheel Drive Automatic 78,000 miles
My 2001 Jaguar S Type has no acceleration above 3k RPM when is in neutral. When running at 40MPH hesitates, above 45 -50 MPH runs smooth on a flat surface. Uphill at any speed starts hesitating. Engine light comes on but code won't register in the computer. Engine light goes off as soon as i reach a level surface or on a decline. I replaced the fuel filter and problem still exist. Any ideas as to what to check or what should be done to rectify the problem? Thanks
