Re: P0171 and P0174, base engine
What the Autel Benz module is telling me is:
P2017-1
MIL ON&Stored&Current
Self-adaptation of mixture formation for right bank of cylinders is at limit value (at idle speed). Enrichment over permissible limit (P0171)
P2086-1
MIL ON&Stored&Current
Self-adaptation of mixture formation for left bank of cylinders is at limit value (at idle speed).: Enrichment over permissible limit (P0174)
Not sure why the Autel and Torque Pro say different things but both show a vaccuum leak as a possibility.
Think I'll fire it up while reading the manifold vacuum on a big dial and just wiggle things looking fo a difference..
