I can't say if this is a common problem to GA16. You computer is under the dash, so corrosion is unlikely. Crankshaft position sensor is used by the ECM only to detect engine misfire.

According to FSM, if injector pulse is not within specs, check: 1. Harness and connector
2. Injector
3. Mass air flow sensor
4. Intake air system
