Keep getting a CEL code 12 (battery disconnected) error. Then it will go away for a day, but it keeps coming back. 12 55.
Also, some times the auto trans will not shift into 4th gear. Presuming the throttle position sensor here, but why no error on that? That symptom goes away after restarting.
Only other flaky thing is the neutral safety switch. Always starts in neutral, but not alw3ays in Park.
ANy ideas?
