Engine Performance problem
1998 Jeep Laredo 6 cyl Four Wheel Drive Automatic 132000 miles
I have a 1998 grand cherokee with the i6. Ever since I bought it it has a cold backfire. If I goose it for a few seconds it clears up. Never had a dtc show up. I have been in and out of this motor checking sensors, fuel pump, coil, everything I can think of. Im thinkin it has a valve train problem because it has a slight miss and hesitant to pick up speed. I also hear puffing out of the exhaust like the valves are worn out. Any pointer would help
have the same problem?
