drove it right after I washed it...no problems...a couple hours later...started it up....rpm's went right up to 2g's...and check engine light came on...idle goes up and down...spudders between 2-3'gs when driving...feels like loss of power...disconnected the battery overnite...next morning hooked it up...no check engine light...seem to run fine...drove it a little no problem...a few hours later...started it...idle went up...check engine light came back on...and we are going through the same motions once again....any clues???
-
Vacuum leak would be my first guess.
-
cel code?
-
I believe is was P0122 and P0123...if I remember correctly....something to do with the TPS low and high voltage?

then it should be the tps, do you have a spare? easy to swap for a test and by the way you describe it makes sense as far as behavior goes.
-
I would check the connector to the TPS. It may have gotten water in it and is now shorting or corroding. I had a Neon where a lot of troubles came from green conductors inside the connectors. Use a blow-dryer if it looks wet inside.
-
Clean up the TPS and reconnected. If that does not work, replace it (it's VERY easy, and IIRC, not that expensive).
-
unless it was hacked those connectors are weather tight so they should not let water in (well, unless the jet was right on it) - doesn't hurt to try though, some dielectric grease would also keep it from corroding in the future.

thanks for all the replies...I ordered a factory replacement...hope to have it soon...I will let you know the outcome...Ron

i did the same thing and had the same problem but mine cleared up by itself after running it a bit. turned out a little bit of water had gotten on the number 3 plug or wire. started doing fine after it dried up and have had no problem since
-
Keep the old sensor and let it dry out for a few days then see if it works. If it does then keep it as a spare. Typically, water is not a problem unless you're using a pressure washer. Although, some hoses do have narrow nozzles. If you're worried then take some plastic bags and over areas where you have to spray close to electronics.

I ussually get a CEL when clean my engine; last time, it was the 02 sensor voltages acting up, but they cleared themselves up...
-
just wanted to update you all...got the new OEM TPS....swapped it out....and the thing runs better than it did when I bought it...must have been on the way out...thanks for the help...im glad there is a place just for us 4bangers... :doggy:
