You can disconnect the battery cables for a couple minutes which typically resets the ECM to some predetermined (default) settings which may make your vehicle run or respond slightly different than it currently does but as you drive the vehicle it will relearn and adjust as needed. If you prefer to wait awhile then it will turn off itself after several --several cycles of the ignition ;so long as the problem is fixed or no longer exists and there are no other problems.

it's probably the crankshaft position sensor. these are notorious on the 6 cylinder gm engines. tell your mechanic to diagnose the car and stop changing parts

Clean all three battery cables and replace bolts. Many starters and batteries have been replaced for this problem!
