This is going to sound strange but you need to have the throttle position sensor (TPS) checked with a scan tool or lab scope.
It has been shown that a TPS with 0.02v or more may cause injector fault codes. If there is a speed control switch input to the Powertrain Control Module (PCM) that is shorted to voltage, it may cause the same problem.
