Engine Mechanical problem
2002 GMC Jimmy 6 cyl Four Wheel Drive Automatic 411000 miles
My daugther bought a Jimmy at an auction hoping to get a cheap winter beater. The engine light seems to go on and off at different times. She took it and had it scanned. It said it was a missfire in cylinder 1.
Changed the spark plugs, wires, router, still having the same problem.
When the engine light does come on the truck runs horrible, sounds bad, shakes. The shop that we took it to flushed the fluids and has gone to the point where they will no longer look at it cause they can't find out why the engine light comes on.
They told my daughter to take it to a dealership to have them look at it but she can't afford to put any more money into it.
Milage is horrible also. Could the cylinder itself be damaged somehow? Could it be a computer problem?
have the same problem?
