Ok, time to replace the CEL bulb then and see if it will let you check the codes.

I've replaced quite a few TPS, it's code 24 and causes it to run rough and sputter. Borg Warner TPS from O'Reilly's limited lifetime guarantee, but you'll need it. After replacing the original factory TPS I've gone through 4 since February. The last time I replaced it, a few weeks ago, it didn't throw a code, but it stalled out when I was driving in front of my house. Exchanged it for another new one and that one was bad right our of the box. I put it in and it threw a code 24, and ran rough. Exchanged it for another new one and ran great.

I don't know how much one from the dealership is, but probably well worth it.

Did you re-set the computer after you swapped the TPS each time? If not, then that was half the problem.

Are you talking about disconnecting the battery cables and touching them together? If so, I did that.

In that case, I'm truly surprised - you must have somehow gotten a really bad batch of them - amazing bad luck!

I am thinking along the lines of post #6, a weakened fuel pump.

Im gonna stick to my idea, I hate EGR's so heres the trick, find the vaccum line that goes to the EGR, PLUG IT ( the vaccum line that is.) 100% sealed, with like a screw or wooden match or something similiar.... Please get back to me, when its something like that, most of the time it will fix it. The way you test an EGR is stick your fingure into the bottom of the egr house you will find hole just big enough for maybe your pinky, stick your your pinky in there, raise rpm's fast and kinda high, feel for the diaphram to move it should move very noticable if little movement then its bad then plug it until you can afford to buy that stupid A$$ $117.99 part... Oh and by the way it may not fix the idle while sitting still but the stalling or near stalling while moving, you should see a big difference... -HBJEEPSTER

No egr on the MPFI. I asked earlier if you repaired the CEL. If not then you haven't tried everything yet.

The check engine light can really help narrow it down.

My CEL showed a bad tps and O2 sensor. Replaced both and runs great.
