Howdy all, a couple days ago i drove my MJ through too deep water. I got it runnin again after gettin the water out of the cylinders and changed the oil. But now when i start it it goes straight to 3 thousand rpms and does not go down. i started it in nuetral and put it in drive real quick and drove it around for awhile. i dont even have to step on the gas just ride the brakes. Im thinking it might be either the tps or the iac. i dont know for sure, i dont know if there might be something that could of gotten wet and cuased this high idle. thanks in advance

If the '89 has the C-101 connector, open up and clean and use dielectric grease. Re-connect. The C-101 connector is located under the hood at the driver's side behind the brake master cylinder.
