Ran into some trouble with my 89 XJ and hoping to get some tips to diagnose it. Finally had the car on the road and now its back in the driveway.
Everything was running ok (didn't seem perfect) and I took it on the freeway to run an errand. On the way (downhill) I started noticing hesitation when coming on throttle. Got to the destination, started it up and took the streets home. As I made my way it got worse and I'd have to floor it to get it to come back on power.
Got almost home when temps started to creep up (I live up a pretty big hill) and I parked it to avoid severely overheating. After it cooled completely down I went back and drove it the remaining few blocks home. Found low fuel pressure and replaced the pump and filter. Starts up much better after this.
The problem now is it runs extremely rough and sounds like terrible. I drove it up my driveway but when trying to get up to speed on the streets the car struggles terribly. Noticeable lack of power as well.
Just wondering where to start given the backstory. The following have all been replaced in within the last year and done under 2000 miles:
- Injectors
- FPR
- Plug wires
- Cap & rotor
- Vacuum lines (almost all of them - picked up the full replacements)
- O2 Sensor
