On your 'vert? That really says a lot about their wires.[/quote]
I've been meaning to get Magnecors for 4 months.

Alright,
i spent the day with a haynes manual (i know i should get a factory but i don't have the money right now) and i messed with the car as much as i could. i found the fast idle cam and it seemed to be working properly - the car revs to three on startup - but once some time has passed the car idles down and still dies when cold. i adjusted the idle so now it idles around 1,300 to 1,400 and jumps to 1,500 - it still idles rough ??? - i was thinking about the exhaust (partly clogged?) and i need to check some of the more complicated parts of the engine (injectors?) anyway i am probably going to take it to the guy who put the engine in if he is home this weekend so maybe he can help. sorry for the long post
btw, does anyone know of a good rotary mechanic in central alabama?

ok guys i took the car to the mechanic and he said that the map sensor was bad, he ordered the part but i won't be able to get it installed until week after next 
. now my only probs are the bad oil pressure gauge and the seat belt light blinking all the time. oh well even if it was cherry stock i'd still be working on it to make it better.

one way to check the 89-91 rx-7's for problems is to run the codes on them. a tutorial for this can be found at www.1300cc.com ...you run a wire from the initial set connector and ground it. then get in the car and turn the key to where the idiot lights come one, but not so the car it startted...the check engine light will flash codes corresponding with parts or symptoms that might be bad with the car. i think scott also has a manual on his site where you can cross reference these. good luck...the bouncy idle does seem like the TPS is off or bad, but run the codes and see what you get...
on a side note, does the car run and rev up ok otherwise?

That's right. i believe it means manifold air pressure sensor, it is somthing to make sure there is a vacuum is side the manifold so as to know that air is going in and not coming out, i think?
