R350 / SL / E
Codes, Parts replaced, runs .... HELP!
09 R350 runs, ruff idle and no power MOST of the time. It seems to lose more power as it warms up.
codes are : p0017, p0300, P0301, p0303. p0305 .
Parts replaced chasing the problem : Coils, Camshaft adjuster magnet (intake and exhaust on passenger side) , both passenger side camshaft position sensor.
Also pulled the passenger side catalytic converter and straight piped it for now,no change other than an extra 2 codes (p0014 , p0302)
Pulled both cam adjusters and the marks lined up correctly.
The car is sluggish starting off and will not climb a hilly driveway after it warms up but once it gets going up to speed , it runs pretty good. Gets up to a 100mph plus.
I'm a bit lost on where to go next. What I have thought of to check is fuel pressure, the fuel filter, pull the plugs (should have done that when i did coils)
What are your thoughts? Thanks for taking time to read this and i would love to get my wife back in her car. R

Have you looked up those codes with regards to the M272 engine, assuming the R350 is gas? Might not be able to find it in the R class section but the M272 was used in a lot of different Mercedes models.
