RX7 FD starts, idles rough, then dies?
Good afternoon/morning.
I'm having a major issue with my RX7.. it turns over no problem.. idles terribly (shaking like crazy) then dies. I try to give it gas when it starts to die but it does not help for long.
I have looked through many discussions on this topic and I have tried a few things to try and get the car running but nothing seems to be working.
What I have Done:
- replaced all spark plugs/wires. The old ones looked rough but still got good spark.
- Checked all the coil packs with a reader, everything seems to be in good order.
- checked for flooding in the engine.
- checked to make sure the car was getting fuel even once started.
- did a (cold) compression test. I know the number will be off because the engine was not at running temperatures, but everytime I tested it I got very similar readings.
- The vacuum lines are all new, and I dont see any that have slipped off.
Issues leading up to this:
I was driving home one day and my front main went. I replaced the main with the engine still in the car. seemed to be running perfectly for a few days.
about three days after replacing the main my throttle started sticking shut and the car would not accelerate. I took the throttle body apart and cleaned it all, worked fine after that.
two days later.. I drove to work no issues at all. when I tried to leave about 8 hours later this new problem started.
I'm not 100 percent sure what to try next..? any thoughts on the topic would be very helpful!
- Thanks in advance.
I imported the car about four years ago now, it has approx 140000xx on the engine. (not sure if it has a rebuilt status)

*What is a "front main"?
*On the firewall just above the throttlebody is bracket with a small black sensor marked "sensor boost" or some such. Has a single electrical plug and a vacuum hose running to it from a nipple on the right side of the upper intake manifold. Make sure that vacuum hose is attached securely at both ends. And that the connector is secure as well.
I believe there is a way to check for codes on the jdm cars but you’ll have to search or wait for someone more familiar with those models.
