Engine Performance problem
1997 GMC Jimmy 6 cyl Four Wheel Drive Automatic 160000 miles
I have a 97 jimmy I was driving on the interstate and the cruise kicked up the motor. After that it has been running really ruff and dies at a low idle runs good at high rpms in park but when u put it under load it has no power. I have change the plugs and cat converter, no check engine lights. I am at a loss with it.
