The battery light will come on and will not shift on take off. The odometer light flashes then it runs fine for awhile but, stalls when the lights are turned on.
Do you

OK when it acts up are you watching the charging voltage at the battery?I have seen bad ecms cause random charging issues. Had a 2004 Chevy cavalier do that and it was a bad ecm because it controls the alternator charging.
