Hi,

I'm brand new to rotarys and this community. I didn't expect my first post to be for help but... I just bought a 94 RX7 with about 25k on a facreman. Everything worked great until - I bought a Mazda compression tester on E-Bay and went to test and see if all was ok inside. Disconnected the 8-10 wire connector next to the power steering pump(crank sensor I think) and then the tube to the throttle body - removed both trailing plugs and did the test - everything looked great 85+ across the board . Buttoned everything back up. Started the engine, smooth idle, will accelerate if the pedal is moved slowly but will stumble and not accelerate if the pedal is pushed too far. On the street will not accelerate if the pedal is hardly pushed!!

Checked for things I could have knocked loose. So my questions are: Any suggestions, Good rx mechanic in the Ventura county area, if only one rotor is operating will the engine still be smooth or can you tell when its not firing like a recip?????

Thanks in advance for your help.

Make sure your turbos are boosting. Check for leaks/cracks in the intercooler piping (everything between the turbos and the intake manifold). If it's having trouble all across the RPM range, Check into your boost sensor, as well as your Throttle Position Sensor. These cars sometimes develop a "3000rpm hesitation," usually associated with the boost sensor. It can be many other things (generally vacuum leaks).

If it's running on one rotor, you'll serriously notice. It won't run roughly, persay, but have a LOT less power. If you can take-off without having to majorly slip the clutch from around 1k - 3k, then you should be okay. An easy way to test is to remove both spark plug wires from a rotor housing. Just remember, Leading is on the bottom, Trailing is on the top.
