It idles GREAT. But as soon as I hit the gas, it stumbles really bad, it hasn't died on me, but it's so bad I can't even get it up to speed.

I only have fuel pressure when the pump is on, is that normal?

The only code I get is for the TPS. I replaced it, and it didn't help. Tried 3 different TPS sensors.

If you saw my other thread, I replaced the Coil, cap, rotor, plugs, wires, Cranks sensor, and it fired right up, But after about 20 minutes, started to run like crap.

The fuel pump sounds good when it's priming.

this does sound like a fuel issue. run some carb cleaner threw (its cheap) it and see if it clears it up a lil bit but kinda sounds like a fuel filter.

I put some Lucas fuel injector cleaner through it, and that hasn't helped so far, I can barely drive it around the block it's so bad.

Is the fuel pressure suppose to bleed down so fast after the pump turns off?

pump should be running while jeep is running. the 32psi should hold for a few minutes at least after you turn the key on.

ok you tried the carb crap no go, possibly filter or pump, filter is cheaper then the pump and easier besides that if you cant think of the last time you did the fuel filter its probly time again. sounds like a restriction but on increased rpm you need more fuel but cant push it threw the filter. if no go then sounds like your pump is about to can you.

Ive heard of this before, may be the Crankshaft Position Sensors.

If you are continuing to set a code for the throttle position sensor, listen to your Jeep.

You still have a problem with the TPS circuit.

By "circuit" that doesn't mean just the sensor. As you have replaced this with 3 different sensors, it is safe to say that the sensor itself isn't the problem.

However, that doesn't rule out the connector, wiring, and even the computer.

Start by spraying the TPS connector thoroughly with electrical contact cleaner (available everywhere). Debris and resistance inside the connector can be a problem. Closely inspect the TPS connector for damage to the contacts.

Still coding? I'd suspect a wiring problem with the TPS "circuit".

Chase the TPS "circuit". Until you resolve that, you are most likely going to chase your tail.

Ok, so my book said code 24 was the TPS. Well the Chilton is WRONG. Code 24 is injector 6. We were messing with it, ended up pulling on the wiring harness while my buddy was moving around, and it died. So we chased it around and found a broken wiring that was just barely hangin on, AND that wire led to the fuel injectors, Soldered it up. And she's running good AGAIN for NOW.

Actually, all of my documentation (multiple sources) shows a code 24 to be the throttle position sensor circuit, not the injector.

But if you found and repaired a broken wire that clears things up, that's great.........

Well, my friend that works at our Jeep store here is the one that looked it up on there system, All Data I think, and found that it was the injector code.

And another buddy of mine that works in a smaller shop is the one that actually found it, and I thought he was wrong so that's why I called my buddy at the jeep store. Not sure if it's updated or what, but my book is wrong. And yours probably is to.

I looked in my Chilton FYI. Not sure if that's what your looking in or not.
