Are there any other things to do?

 

Sure, study the OEM tech section to learn about your rig and buy a service manual from Jeep,Chilton, Haynes or some such reference to educate yourself. Then follow along with things of interest here to learn more. You'll be an old salt in no time.

If it's the TPS it just needs to be replaced. Does your xj have a tow package, if so you might want to look for that comfort switch again

 

Nope no towing package or button for transmission. And its not getting better I put fuel injector cleaner in it when I filled up. And today accelerating I was pushing 3000 rpms. Going 40 I was at 2000 rpms...

 

Well it makes sense for your rpms to be higher at acceleration than at cruising speed

 

"Houston, we have a problem here!" zlnk7, the problem we are having is that the language you use to describe the problem isn't technical enough or clear enough for us to be able to help you constructively. Which is why I suggested the manuals and reading here. The language you use to describe the problem doesn't sound like a problem but we know you have one or you wouldn't be here, them we try to guess what you are describing and give you a guess based on our experience which is evident from the quote above. Now, the relationship between the RPM and the speed is interdependent upon the relationship between your foot on the accelerator and your problem. We can't begin to know your foot experience no matter how much you describe it nor can we just know your problem without being there. So that leaves us with RPMs and what symptoms that you are noticing that indicate the problem. To be able to advise we will need more technical analysis of the symptoms. Perhaps: "When I push the gas pedal the engine goes up but the Jeep doesn't go faster like a normal car." No technical language used but describes a symptom.
