About two months ago, I had a problem with the throttle sticking high. I could tap on the gas and it might go back down or it would stick higher around 2200 rpm's. Finally it felt like gears were slipping (the sputtering feeling). Engine light came on and I took it by Advance Auto to get the free diagnostics test ran. They told me that it was the TPS. So I replaced it. About a week later, my throttle starting sticking again. Know engine light came on again, along with the sputtering when I give it gas.
Any idea's? This is a 2000 TJ. 4.0 Liter
