my car stumbles/bog at ~3200 rpm.
 

i have to check the secondary injector pulse. i have checked the grounds on the car. they are now clean. is there anything else i need to look into. car runs fine under 3200. and on a side note whats the best way to remove the oil pan without pulling the engine

read my posts on oil pan.

Verify operation of 5/6 ports.

im new to rotory engines but i dont think my 87 t2 has the 5/6 ports i think its 4 ports

Yes, you are correct. It being a TII is good information to know for first post FYI.

I am not as well versed with TIIs but you are on the right track with checking the secondary injectors, that would be my next move.

Yeah I forgot to pit that in the first post. My bad

Ecu ground under the manifold double triple quadruple check it
