Hey, my car is having some management (I think so) problems and I can't stand it anymore.
engine is m20b28 with m50 management and chip.
Sometimes when slowly accelerating, till 1.5k revs it goes smooth, and then it starts to like loose power, poorly increases revs and then when it reaches 2.5k rpm's starts to rumble again :grin: and in that 1.5k - 2.5k revs range it sometimes just starts to twitch car so hard like to back and front that you just have no other choice than release clutch and stop that shit :grin:
also sometimes idle is very rough and rpm's drop low about 500.
and somethimes when driving I release gas pedal, car bangs exhaust like mad turbo car running veeery rich? why?
Diagnostic doesn't show anything, AFM looks like working, Lambda sensor ok, tps seems like wokring too, etc., only I dont have cam sensor.
fuel pump is fine pierburg 3.8 bar, fpr 3.5bar, green top m50 injectors, bosch platinum sparks (with ngk's it was all the same problems).
maybe some coil problems? or injectors? (before installing I checked them and they were fine about 3 months ago)
please help, and sorry for my bad language :giggle:
