Fuel Problem
My '03 Z has never started on the first try. Took her in and they said it was a fuel pressure issue. They changed a relay.
Took the car home and the next day I got a check engine light and the following codes:
P0171 H (Fuel Trim System Lean Bank 1)
P0174 H (Fuel Trim System Lean Bank 2)
They were history codes when I checked. I reset the codes and of course...everything is clear. Started it up but haven't driven her yet.
At what point should I take her in? Is a 1 time code justification to bring her in? Any clues as to what might be going on?
Thanks all!
