Ok, I will say this one more time. The Tps controls the tq converter not the tv cable. When you press on the pedal it sounds like the tq is locking up thats why its hard to accelerate after you have let off the gas.

Now I am not 100% sure on this because I havent driven it my self, But I do know I had simalar problems with my 90 XJ and it was being caused by the TPS.
