XJ Stalls Under Light Accelleration
My jeep has stalled twice now in the past couple days. Each time, I was accellerating. The engine idles and cruises fine. I can shift into neutral and restart the engine without and issue while still rolling.
Also, the transmissions shift points seem to change a bit lately. One morning it wouldn't shift out of first until the engine hit 3000rpm under light throttle application.
Am I wrong in blaming the TPS for both issues, or do they seem like two separate issues?

yeah... fuel pressure would be next to rule in or out. Just make sure to test not only at idle, but driving too... including accel and decel as well.

The fuel filter has been on my mind for a while since I've never changed it, but there's no hesitation at all. The FPR was new in January.

I have never indexed the distributor. I'm not really sure what all that entails. I'll pop the cap off this morning and see if it needs to be cleaned up.

The rotor and contacts in the distributor were pretty crusty. I cleaned them up, but I will still get a new set.
I'll check out tip 13 when I get a little later when i have time.

Looks like checking out the distributor will need to wait until Friday when I have the day off. I'll be getting a new cap and rotor, too. I don't have a vise. Will that be an issue?
