JUST BOUGHT A 93 FD WITH 96000 MILES. THIS CAR IS MINT, NEVER SEEN SALT, AND RUNS VERY STRONG WITH 10 BS OF BOOST. IDLING IN NUETRAL AT 1100 RPM SMOOTH. PUSH IN CLUTCH, SMOOTH. SHIFT INTO GEAR WITH CLUTCH IN AND IT LOPES ETWEEN 100 AN 1400 RPM. ANY BODY KNOW WHATS UP?

 

MISPRINT. THATS 1100 AND 1400 RPM. I DONT HERE ANY AIR LEAKS, AND TO THE BEST OF MY KNOWLEDGE, THE CA IS COMPLETELY STOCK

 

I was told by an RX-7 knowledged guy that if it idled funny to stay away unless you are prepared to fix some probs right off the bat. THe first FD I test drove did that same thing. That car had mods like Blitz BOV, Blitz SMIC, Apex S-AFC etc. Car pulled hard, but I stayed away. Ended up finding out lots about that car. Phew good thing I didn't by it!

 

This is very common, and shouldn't be hard to fix. It is probably the "clutch swtich" or the "1-2 switch". Do some searches for these and you will be able to learn more.

It could also be your TPS (Throttle Position Sensor) out of adjustment. This is also fairly easy to adjust. Do a search to learn more. Again, very common.

PS- This is not necessarily a sign of bad things to come, despite what some might say.

thats right...he told me about the tps... thanks for the reminder.

 

It's probably the clutch switch -- a cheap and easy fix.
