Hi team!
I recently bought a problem....... I have been toying with VWs for ages but this has me stumped! have a mk6 R. engine is running rough and rich! Doesnt hold a steady idle fluctuates a fair bit. revs fine (backfires due to rich problem) drives fine.
the car has a stage 2+ APR tune. There is a APR sticker on the HPFP
When I scan it. it comes up with misfire codes on all 4 cylinders. Plugs all look the same. when i drained the oil it was definitely contaminated with fuel. i drained over 5L... so a fair bit of fuel mixed in with the oil
PCV - a common failure on these looks new. although that usually causes a lean condition not rich.
Anyone got any ideas of how to narrow down the issue?
Cheers
