hey everyone. i have a 93 5spd xj, when it gets to running temp it will stutter/bog down then surge back to power. it starts normal hot or cold, i have replaced fuel filter, plugs wires, cap rotor. i cant afford to keep throwing parts at it and im in need of some advice. thank you

 

Hey man I have the same year 5 speed with the same issue. I posted a thread a few days titled "help diagnose my hesitation" in the stock oem tech forum section. You can find that if you want to see all the answers but mostly agreed upon was the TPS or throttle position sensor. There are ways to test the voltage but it is most likely the culprit. It's a 35ish dollar part from the store and an easy swap.

 

o2 sensor.
