I have an SR20 in a 92 nx

Car will start idle and drive untill you go above 2000 RPM. once above 2000 RPM misses like crazy.

coil tests good
MAF test good
TPS tests good
plugs, wires, cap, rotor, power transistor test good
Harnesses test good.
I hear fuel injectors working.
Vac hoses are good with no leaks detected

although I do get Code 21 on the ECU???
it seems everyting that would cause code 21 is working but still lots of missing and no power above 2000 RPM.

Any help would be appreciated
