98 3.0L OHV transmission/brake help
 

Hi, everyone, i'm new to the forum and have a problem. on my 98 taurus lx i have a stangesorta grinding noise (sounds as if break pads are worn out and your hard braking). When driving witht he car and applying the breaks the car cars seems to be not disingaging the trottle/transmission. I get the above noise (brakes were checked out and are fine) usually when braking and the rpm's don't fall under about 1200 rpm. it seems as if the car is still trying to accelerate. I've cleans and greases the trottle lines and what not but it still does it. my father went to the dealer and they think that (he thinks) the trottle body (butterfly) has to be replaced or that "valve" that's placed above the trottle body. also, while cruising at any speed, when we place the car in nuetral the rpm's don't fall down to idle like they do in all our other cars.

But i was wondering if anyone else has this same type of problem and what you did to get it fixed.

Thanks for the help guys

Dang, I was thinking you had a vac leak or that you had a problem with the idle control.
Did you have a check engine light? What was wrong with the TPS? was it open, or shorted?
are was it causing the throttle plate not to close all the way?
Sorry we missed this one, but info apperciated :eek:

The check engine light came on a 2 times and this problem has been present for 5 months, but my father took it to the dealership and they said something about the computer has to be reset with a new program or something like that. and since then (4 days) no check engine light. my father talked to a guy at advanced auto parts and he recommened a new idle control valve or the throttle position sensor. my father tried the idle control valve, and it still did it. so he went back a got the TPS and now it's okay. I don't know what was wrong with the original TPS and i'm not to sure about precisely what the car was doing, partly b/c it's not my car and my car has a SMG transmission.
