its possible that the secondary injectors dont come online for some reason, unlikely but possible

If it was the secondary injectors, wouldnt i notice that at about 4k when they activate? And I also found out that my alt is bad, thats why it lopes and when it lopes all the idiot lights flash and the volt meter drops. Some guy told me that when his alt went bad he could rev past 3k could the alt cause this problem? And how do I check timing on a rotary engine? what is there to time besides ignition and how would adjust that?

and yeah compression check is a must before you start pulling your hair out... if the results come back positive then you can justify going crazy.

well the ecu needs power to work right, and they dont like ow voltages. before you condemn your alternator, check all the battery/ alt connextions they get old/dirty and cause all kinds of wierd problems

Def test the alternator. As far as the rev thing, my GSl=se would go past 6. Turned out it was a clogged cat/s I replace them with racing beat header, high flow Catco cat, Generic ebay can muffler. Now it revs freely.

When you couldnt rev past 6k did it feel like you were hitting a fuel cut? And like a pulsating jolt like you riding fuel cut?





I dont think compression is bad because it feels good like al the other NA Rx-7's I drove (including one rebuilt) up intill 5.5k.
