Symptoms of a Throttle Position Sensor Going Belly Up?
 

What would be the symptoms of a bad TPS? How expensive is a
replacement (4.0 litre Cherokee Classic) and is it a DIY job for the
moderately skilled backyard mechanic?

Thanks.

Bad performance/response in all situations. A closeup of the TPS can be

They are easy to replace but you should be looking at everything
before swapping parts.

Pull the codes first. http://members.cox.net/wilsond/engine_codes.html
