Check Engine light for codes P0170 and P0173
I just bought a 2000 MB E-320 with 48,000 certified miles. The Check
Engine light lit up "for a P0170 &P0173 stating that the fuel trim in bank 1
and bank 2 are not where they should be" The car has had an OE new
fuel pump and fuel filter installed. What else could it be?
thanks
