CODE 232-NO OTHER CODES AND CHUNKY IDLE ON B234 ENGINE 700 1990

posted by  someone claiming to be Scott on  Wed May 12 03:20 CST 2004 [RELATED]

I have been reading the archives about this code and nothing really sticks out,I can reset the computer and the code stays away for a couple of days then comes back.I have replaced fuel pressure reg unit and resealed injectors and intake manifold with no improvement.The O2 sensor swings from .1-.75 volts at idle,but idle is still not what it was years ago,this car has around 170k miles on it and the idle feels like a lean condition as when you come to a stop from a cruise there is a momentary stumble untill the idle corrects as if there is a momentary lean condition on decell.With no ex gas analizer I am just guessing at this time,there are no vacuum leaks aparent and throttle body switch is adjusted porperly and throttle plate is clean.I we could fix this problem on this board it would be a good one for the archives.
