Still without my car. Can anyone tell me if by not disconnecting the negative battery cable after installing a new TPS and transmission solenoid that it could create the problems I'm having? A friend told me this needed to be done to reset the computer. Is it now too late to reset. Could anything have been damaged by driving it without having "reset" the computer? Thanks

He has rechecked all vacuum lines, hoses, trunk wire, etc and still no solution. He says there are 2 TPS on this car and is ordering the other to eliminate the possibility the new one (that threw the code) is not working with the one he did not replace. He put the old one back on and it brought the error code back. With the new one on it eliminates the code.. He will have the other TPS tomorrow. Thanks

I appreciate all the responses. Unfortunately I will have to wait until Monday to tell him to try these ideas. It is locked up in the garage and they don't work weekends. If anyone else has a suggestion, I will try anything. I will let ya'll know if any of these tips worked once they get back to work on it. Thanks again.

Thats what I am thinking. That is why I came here, to find out some of the things he might not have replaced when doing the original repair. I will ask him. I don't mind if he is offended by suggestions because he is lost right now.I am already into this repair for $700.00 and need to get my car back. Going on 2 full weeks. Thanks for any help.

Thanks for the response. He says he did clean clean the throttle body and even installed a second new TPS and then reinstalled the original, all to try and correct what is now happening. He thought he may have received a bad part. He has a similar Lexus at the shop and has been comparing the settings but nothing he has tried has reversed what replacing the original parts apparently created. It had never stalled or idled rough until he replaced the solenoid and TPS .

Please help me help my mechanic. I have a 1995 LS400. Codes recently came up for the transmission solenoid and throttle position sensor. The car had been shifting hard and strange so I thought it made sense. Since replacing both of them the car has immediately taken on a new set of problems, with no new codes appearing. It idles very rough at start up and usually will stall out. If I do get it going it stalls out while driving down the road. My import mechanic says he cant figure it out. Any help on what could have happened by replacing the two parts mentioned? Thanks
