Poor newbie in need of diagnosing engine performance issues
So this is gonna sound like every thread ever posted by a newbie... but here goes, my RX-7 runs like crap! I need help! It spits and sputters and stumbles and backfires. I've done all the tune up stuff I thought would help (new plugs, wires, distributor cap, rotor) and it made no difference. Is there something glaringly obvious that I just don't know about rotaries or what? I would really appreciate any help, thanks in advance.

Welcome to the forum. If you don't know anything about how the rotary works check out the faq page where it will tell you about it from howstuffworks.com. Good info. Check the faqs, archives and the search button, they will help you out big time... us too. Replace the fuel filter, and check the shutter valve. Change the spark plugs too. If fuel filter don't help then try plugging the vacuum hole in the air filter box closest to the driver side. Helped me out. thats the shutter valve... and when goes bad describes what your going through. God bless

Welcome to the forum and the dark side.
In my sig line is a link to the online FSMs, carb manual, etc.. Read/download whatever you need.
Fuel filter is located underneath the body, near the left rear wheel. Timing is the same as any other engine of the era, except you get to time it twice and setting the trailing is different, but not difficult.

Wow, what a difference a fuel filter makes! I'm sure the fact that the timing was WAY off had a lot to do with the way it was running too. Thanks for all your imput folks, my car really appreciates it!
