Ready to race!
I've had this code before, and pretty much ever since I went Stage 2 APR (I think that's when it presented). Usually happens at 6k+ RPM, but also happens sitting at 4k RPM in 3rd for example. CEL flashes and usually stays. Occasionally it sounds like 1 cylinder isn't firing (sounds like a subaru). Seems to make 15-18 psi as normal. I don't notice abnormal power on the initial pull to 6k+ RPM.
I have done:
I don't know if it is relevant, but some days the car pulls strong with quick boost. Other days it feels like it's sluggish and slow to spool.
Should I check the valve springs? VW mechanic told me it was likely the case before I got my carbon cleaning. Went to a specialty shop and they said it was unlikely the valve springs, but likely carbon buildup and/or injector(s). Roughly 10k before this I was told by another VW dealership my carbon buildup was completely fine (they checked during intake replacement).
Could a timing chain stretching cause this?
Any other ideas?
I have done:
- New plugs and gaps (OEM and aftermarket, from 0.24-0.32 gap)
- New red top coils (total of 5, moving coils didn't move code)
- New injectors (didn't know about extended warranty, paid out of pocket)
- Carbon cleaning (walnut blast at a shop)
