i am pretty rotary inclined now, but need a little guidance...
i met a guy here today and was trying to buy his 94 fd with only 50K on it, and almost had min convinced.
it is an automatic, and he is having some rpm related issues with the tranny....
1. lumpy idle.....i can handle that...
2. when the car is put into gear, the rpm's ROCKET to 7500rpm......
3. see number 2.....
4. seenumber 3.....
...and so on....
can anyone point me in the right direction? could it be a tps or an auto tranny computer problem? i am going to look at it tomorrow, and need a little info before i go.....in the meantime, i am going to consult my manual...
thanks ahead of time....

Yeah, it could be the TPS. Go here to see how to adjust and test it. http://www.scuderiaciriani.com/rx7/TPS_adjustment.html Very simple. All you need is a voltmeter and a safety pin.
It also might be a very bad vacum leak, like one of the manifold gaskets blown out. I dunno?
Dont you already have a highly modified FD xplicit? I guess you want the auto for a daily driver.

i can handle the TPS, and that of course was my first thought......i have a multimeter and plan to check it in the morning...
i do not think that a vacuum leak would be gear shifted specific.....

Sounds similar to my friends auto' and he had the EGR replaced. Check the ECU error code and look it up.

Your not getting a check engine light? If it was any of your sensors then you should be getting an error code. It happened to my friends 3rd gen(manual) it was the TPS error code and it just had a bad connection. That was all.
