I have been struggling with a low RPM idle and a check engine light for lean fuel mixture on banks 1 and 2 codes P0171 and P0174 for about 6 months now. My question is, can bad vanos seals cause a check engine light and a low RPM idle? My car has 140,000 miles on it so I assume they should probably be changed anyway, I've just been putting the job off for as long as I could.
