problem after 5500 rpm, need urgent help

RE: problem after 5500 rpm, need urgent help
thats what i was thinking too, but lets say there is something like a bad vtec, than to car woulnt be worse when the vtec engages but would just wouldnt improve as its supposed to be, but my revving slows down...
so i dont think it a bad vtec even if there is such thing

i dont know about other vtec engine models but inside the d17a2 engine there is a filter inside the the machinery the encases the vtec at the end of the cam, somtimes that filter get dirty , u may want to look into that. just and idea.

i think its definatly something with the A/F Ratio, its either gettin too rich when the vtec engages or too lean. also its theres black smoke coming out from time to time from the exhaust at high rpm.
Going to change the o2 sensor with my friends to check if its the o2 sensor or not.

RE: problem after 5500 rpm, need urgent help
ok i connected a wideband, when the car slows down it over fueled, so its too rich i mean really really rich, and around 7000 the air ratio goes to arond 12. , so the problem is over fueling, but why ?
ive some parts with my friends car.
-o2 sensor
-regulator
-enjectors
-inlet temp sensor
-map sensor
anything left connected with the fueling?
Could there be a problem with the ecu? we changed the ecu's too, but they would start with different ecus.
so i still need help...

i do have the right ecu but i was thinking maybe it ha a problem.
i do not have a fuel pre. gauge. but i dont think its from the fuel lines, like pump or regulator, because they are standard.
