Fuel Trim Question??
'96 Audi A6Q with approx 147K miles - now giving me the check engine light with two codes:
PO170 Generic Fuel Trim Malfunction - Bank 1
PO173 Generic Fuel Trim Malfunction - Bank 2
Any ideas how to correct? I'm thinking potential vacuum leak or dirty fuel injectors, with O2 sensors next likely culprit... Appreciate any advice from the peanut gallery. THANKS! Ron

If you search for P0170 instead of PO170 you'll have better luck finding the answer to your question
the second character in your DTC is a zero, not the letter "O"
