Idles too fast-1996 4.0
My idle has increased from 600 to 750 RPM in drive. Is this an indication of a defective Throttle Position Sensor. These are over $400 on E-Bay. Do any of you know if this sensor causes this. My CPS and Idle Air valve are new. Amazing that the sensor for the 4.0 is so expensive as compared to other TPS on cars. Any advice would be helpful

Ragjag,
My first thought would be to look for a carbon coating buildup on the throttle body which is keeping the butterfly slightly open thus raising the idle. Try cleaning it gently.
Next thought is an air leak somewhere on the inlet side. Go around with a spray and check every possible joint area whilst the engine is running.
Just to let you know, a new throttle potentiometer (JLM12074) from Jaguar is £141 so not sure why people would ask $400 on ebay.
Good luck
Paul
