Today my car went nuts. First off P0103 mass or volume air flow circuit high output has come on twice in the last few weeks Next P0335 crankshaft position sensor A circuit malfunction, P0336 crankshaft position sensor A cicuit range/performance,and P0410 secondary air injection system malfunction show up and made my car die while on the road. Had to cruise in neutral and it fired up. I have hptuners and ran a scan and these codes showed up. Went to a local shop and checked to see if the sensor came loose or burned. Nothing. Erased the codes and drove 100 miles and ran fine without setting another code. Should I be worried?

 

Still ok, but still wondering why this happened.

 

I would suspect some sort of power / ground hiccup
that messed up these sensors' output enough to trip
the faults. Might check for loose / crusty grounds and
so on, just to show her you care.
