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.

This could be anything, spark plug wires/ the injection spider in the intake manifold. Have a pro look at this before you spend unecessary money on things that you are guessing at.
