i have a 90 300zx automatic. pop charger, new spark plugs, two new injectors with different colored dots ( 4 black 2 blue). Well the car starts up a little hesitant at first but does come down to normal idle and sounds fine at idle. Upon Quick acceleration it bogs down and slowly accelerates through the rpms. I have cleaned all the connectors that i can see and can confirm the idle sensor is at .44 volts and 3.9 volts wot. When i bought the sparks plugs i got them at checker auto parts and they have way smaller medal pieces at the end something new i guess would this cause the quick acceleration off the line problem? All coil packs ohm at .8 to 1 ohms temp guage shows middle of guage and oil pressure is at 30 or 40psi on guage at idle and about 60 or so upon full acceleration. I have added tape to the pop charger filter on the bottom to see if that would help but no good still heavy bog down when peddal is pressed to the floor of the line. timing is at about 15 last time i checked. any other suggestions to check? would be helpful thanks and i am sure you get this type of problem all the time. Oh one more thing i show no error codes from ecu just a code 55 and the weird thing is that the knock sensor wire is cut in the engine bay why would this not set off a code?
