My biggest concern would be engine issues, but it could also be an incorrectly installed crank sensor, timing issues, or ignition issues.

Hi there,
The trouble code P1391 points to two parts which is a bad crankshaft or camshaft position sensor. You might want to check the top three possible sources of the problem.
1. Random misfire/stumble/bucking/stalling, often over bumps or right hand turns or when going into reverse.
2. Shorted (out) fuel pump/ECU power wire.
3. A improperly indexed distributor/cam sensor may exhibit surging, light bucking or intermittent engine misfiring.
