yes i did search but i cant find a clear answer. seems like this only happens to b16. this is what i got. d15b2 mpfi swap 91 civic sedan. pm6 ecu crx si dizzy. getting a code 9 (cylinder position sensor) i replaced dizzy checked the ohms and continuity and it checks out. when i first did the swap the car would bog down horribly from idle and backfire from the intake. it still bogs a little bit wheni hit the gas hard.nothing very bad though. around 2500rpms and 3000rpms i get a hesitation, engine will jerk then its fine. car runs great in my opinion. just dont know what this hesitation is all about.. for the b16s it seems like its the o2 sensors are switched. but what could cause this in a d15b2 mpfi swapped??? timing?, eacv?, tps?, pcv?

 

???

 

i know there are tons of threads about this but iv read them all and i havent got a clear answer from them.. exspesially for a d15 mpfi swapped

 

just cleaned out the eacv and now going for a drive.. it doesnt bog anymore. but i dont konw if it will hesitate still or not. i hope not.
