wideband is a glowshift and i am running stock injectors. i haventput anything into the fuel system not even a fuel filter.
where is the wideband o2 sensor mounted?
EDIT:
also (assuming is not a fuel pressure issue or that your o2 sensor has good ground and there's no electrical problem on the signal wire),
1. which one did you get? is it the one with analog (datalogger) outputs? if so you can delete your factory o2 and use the 0-1v analog out from your wideband.
2. did you calibrate the wideband with the sensor out of the exhaust (not installed) - it is probably the best way to calibrate it, if you did it with the o2 sensor in the downpipe i'd say remove it and leave it out during calibration.
