'92 T-Bird help

I have a '92 t-bird 3.8. non sc. The other day while I as driving the engine started revving high(2500rpm) while I was at a stop light. Then, it tries to take off on it's own when I release the brake. In neutral it also revs high. However, the tranny wouldn't shift pass second, It will only rev higher if I give it gas. Now when I start it, it revs and it has a grinding type noise like the tranny is in gear.Any suggestions? Thanks.

Could it be the mass air flow sensor?

Re: '92 T-Bird help

Alright, I fgured out why the tranny wouldn't shift. So, all I need to know is why I need to hold down the brake all the way at a stop light, or else the car will take off on its own, without giving it gas. It also revs at 2500 rpm on start up.

I would check the IAC,(Idle air control valve). It may be sticking.

Had the same problem with my 93. I had to change to Idle Air Cont Valve. Solved my problem.

Re: '92 T-Bird help

Not to jump on the band wagon, but im agreeing with mech8251, from my hours of research on the very same issue in my 89 sc most point to the Idle air control, I am going to replace mine very soon and i will post my results here and on my Super coupe High idle thread, my plan if that doesnt work is next replace the mass air sensor, then a third option, the tps (throttle position sensor)
