I have a 83 STE with an 2.8 Z E2SE carb with drivability problems - hesistation, surging and rough idle. The problems looks to be from a lean condition caused by the carb, because when I disconnect the mixture control solenoid (max rich) the drivability improves. This includes both open loop and closed loop modes. I've checked most of the obvious stuff- vacuum leaks, plugs, wires, ing timing, fuel filter, O2 sensor, Mix control solenoid, and no ECM codes. So the lean condition seems to be from a problem in the carb. Anyone know if there are any typical failures in the carbs that would cause this?
