Hello all. It seems like i might have some bad news. I have an 89 Jeep Comanche with the 4.0. I had some rough times recently getting her running. I finally got her running (replaced everything cept the TPS) but now i think it might be acting up. I put in new fuel pump. Now i have a high idle. Never had one before it always idled about 600 rpms now its about 2000. This cant be good. And sometimes when i first start it it wants to miss and kinda backfire. Plus i have noticed it seems like i have NO power whatsoever. PLus i think that OD is slipping. (automatic) It used to run about 2k doin 65 on the highway. Now if im on a flat hill its about 2500 rpms and if i have to go up a hill or give it more gas it goes up to 3000 rpms. I just thought it wasnt goin into OD but i pulled it down into third and it downshifted so it was in OD. I know this tranny is computer controlled and it didnt do this two weeks ago and i havent driven it more than 20 miles. The only thing that i have done to it that is tranny related is i accidently broke the kick down (to kick it down a gear or two when i give her hell) and i dont think this could do anything, all i have noticed is that it wont downshift when i push on the gas hard. So im wondering if there is anything cept a tranny that is going out that could cause it to slip in OD? the fluid is fine and most of it is fairly new(blew a hose and had to replace 3 quarts) so im at a loss
