since it is not doing this for the moment, you should disconnect the battery to clear the code (leave it off for 5 min or more) and if it starts doing it again check the code and see if it's the same.

Update......
I checked all grounds on the body and engine. Found one loose on the passenger side on the engine. I cleaned it off and tightened it down. This still did not solve the issue. I ended up replacing the TPS. That still didn't fix it (but it fixed my idle problem). I checked the pcm connector, wiggled the wires and it didn't effect it. When i wiggled a group of wires that connected to the tps and others close by it would die.  I ended up taking all the connections off of each sensor and checking each one then I put them back. I have since test drove it twice and also hit some pretty hard bumps and nothing happened. Hopefully it was just a bad connection. We'll see if it acts up again in the future.

Started acting up again on my way home after I got my new front and rear axle put in. Checked all of the connections on the sensors under the hood, wiggled wires on the pcm, checked all grounds again. Cant get it to act up by wiggling wires. Any more ideas? I already replaced the TPS.

did you get any code again?

[lqdtrance]

Same codes as before, 12 and 33

hmm, you are definitely having an electrical interruption (losing voltage) - especially that you said you found a group of wires that when wiggled would die - not sure what else to suggest other than what i already did, seems that you have a problem with the under-hood wiring harness, you could try and find one from a wrecker's (including the distribution box), but stranger things have happened so i can't really say will solve your problem 100%.

The funny thing is that when I wiggle the wires nothing happens. I think I need to do just that and get a new harness. Are they expensive?

[sharpxmen]

i got one for $20 as i needed some connectors and i butchered it, but i heard of something like $100 for a good harness. I guess it depends how many are in the yard. most of the vehicles i have seen are missing some connectors or some are ripped off when they pull the engine, so probably best if you find one that still has everything on.

We'll see how it goes. I need to replace some other sensors before I do that anyways. I have to replace my temp sensor. I remember now that I brought my jeep to a shop to get the Fuel pump and sending unit replaced and ever since then this has happened. Not only that but I ran out of gas today and my gauge showed a half a tank. I need to call the shop up and have them fix it. Only problem is that the work was done over a month ago.

On the bright side, My Jeep now has power steering!! I just installed a power steering unit today. What a PITA that was.

maybe that i'm just used to it but i have no idea how you managed to drive w/o power steering, must be that you're working out lots

It was a def. work out especially off road.

any update on the problem??

[lqdtrance]

Not yet. I am getting the codes read tomorrow at the dealership. I am getting mixed stories and dont want to waste money replacing parts that dont need to be replaced. However, this problem started after having the fuel pump and sending unit replaced. It could be a short back there. I was told though that when replacing those you need to have them calibrated to run right with your Jeep. Any truth to that?
Anyways, I hope the codes will tell me something. If not then I plan on bringing it back to the shop where the pump was replaced anyways because the gauge doesn't work properly. I ran out of gas when my gauge read a half a tank.
All in all if it is not that then I'll focus on the speed sensor and the wires in that area. This is really pissing me off. I didn't get to run my jeep in the mud bog this year at the 4 wheel jamboree. Just wasn't running good and I still had to be able to drive it home.

Here's the update. Oil in the distributor     All better now. Cleaned it out and she hasn't acted up not one bit.

Now I just need to rebuild my tranny!!

do you think it could've been the connector? can't imagine how oiling it would make it better (it's either rotating or not) unless you have some excessive play in the shaft or something. What do you mean by cleaned it out - this is interesting so give us some more details please. good to hear that is running fine now.
