Completly Confused, Stalling after 4000
Car runs like **** right around 4000 rpms up. No power, very slow. Tried fuel filter, plugs, Tps, Afm/Maf, All Sensors good, Got Fuel, Got Air. Take foot almost all the way out of pedal runs good. Not sure where to go next. Acts like a Tps on a piston motor, not the problem with rotory. Any one have any ideas plz help. N/A Fc

have your checked your secondary injectors since they only come on about 3500-4000 rpm.
check the connection to the ecu and to the injectors
also get a used ECU and swap that out.
also they might be blocked so get them professionally cleaned.
also change your fuel filter since it could be clogged and flowing enough fuel.

Also if its a non-turbo check to make sure your aux. ports are opening up. If not they may need a thorough cleaning.

The aux ports wouldnt cause it to run like crap. I've run my car with the aux ports not working at all, and with the wired open, and it still runs fine.
Its almost definately related to the secondary injectors, as NZ said. My car is doing something similar, and I'm pretty sure its a clogged secondary. To fix it, just follow the steps in the haynes manual/fsm. If you dont have either, you can find the FSM on www.iluvmyrx7.com It's chapter 4.

The secondaries are very easy to check on NA's, since they sit right up on top of the LIM. Make sure the electrical plugs are clean (inside) and secure. Measure the impedance of the coil with a DMM, it should be 12-16ohms. If it'snot and electrical problem one of them may be clogged, in which case you might as well remove all four and have them professionally cleaned.
