i have a 89 civic d16z6 swap. it runs perfect when engine is cold and until engine starts to warm up it'll bog? change dizzy 1 weeks ago, fuel filter was change about october last year, put in 255 warboro fuel pump last year during november. I"m using the f22 injectors.


This only happens if i use my p28 ecu but if i use p06 chip up ecu if don't have this problem. could it be my ecu? i hate running the po6 ecu because the p28 runs better and stronger... from my theory.

any help.
