Hey guys! This is my first RX-7 so excuse me if I seem a bit ignorant. I have very little experience with the rotary engine platform car. I drive a 1991 FC with a Turbo II swap. I'm having a strange issue and as far as I have deduced it has one of three problems, but I am thinking someone more experienced could clear things up for me a little more since I base my theory of a regular piston driven motor.

The motor is not idling correctly from what I can hear. When I drive after about 15 miles or 20 minutes the motor will hesitate at 3800rpm's and I need to restart the car and the unit is running fine again.

We have tried replacing the ECU and it didn't help... Which leads me to BELIEVE that either the secondary fuel injectors are not engaging, the fuel pump is congested, the throttle positioning censor is bad, or there is a screwed up ground somewhere in the motor assembly.

I was hoping someone could shed some light for me? Also, i live in Los Angeles so if anyone knows any good mechanics that specialize in Rotarys in the area I would appreciate any and all info. Thank you!

Try pulling error codes. There is a single(Orange colored wire), wire check connector located by the leading coil. Ground this wire and turn the key to on and this will cause the error codes to flash on the idiot light box.

 

Thanks bro! Ill give that a shot later today and post up how it goes, meanwhile, i'm open to other suggestions.

 

Well, i've been pursuing my own stalling problems so i've gained a bit of experience over the last few weeks.

I'm yet to put everthing back together so i don't have conclusive info but check your HT leads for corrosion, the coil pack connections etc.

i had a lead that was corroded to it being green!
