1994 Jeep Grand Cherokee
So my 1994 Jeep Grand Cherokee while I am
driving my jeep kinda jerks back and fourth and it
only does it when I've been drivin for 20 minutes or
longer what would the problem be? We have
already replaced the plugs and wires.
I had one come into my shop doing somewhat the same thing, once you got up to speed and started to cruse down the road at a steady speed it would start to buck, anyway found it was the TPS a lab scope showed all kinds of what you would call electronic noise, replace th sensor, no more noise and the problem went away. Just a thought. Should have a good shop check for sure though.
