So here's the skinny. Just installed an ETs kit and got tuned today. Tuner is legit and made a nice 485/373. Shop was 100 degrees and 40% humidity.

Upon starting, a little oil around the hot side/downpipe burning off. Assumed it was turbo assembly lube, etc burning off. Drive to the shop proved that and no more smoking or oil visible. I had the exhaust cam sensor wrapped in heat wrap for protection.

Maybe 10 runs on the dyno. Maybe more. Got dialed into the above power at 26psi. No knock, nada. I drive home and about 5 miles from the shop, I throw an SES. Back to the shop, no visible breaks in the cam sensor. Clear codes, on my way. Again, 5 miles away, SES. Same codes. Too rich and exh cam intermittent.

I cleared the codes at the house but keep returning. I'm thinking upstream O2 is fouled with oil. The cam sensor hot. But, happened again, both codes, after 6 hours of sitting.

Going to see my tuner tomorrow but any ideas in the meantime?

 

What are your idle AFRs?

 

^that would help

Is the car acting erratically? Any issues with idle or partial throttle cruising?

Simplest would be cam sensor going bad.

 

Thanks for the replies. idle AFR's bounce from 14.3-14.9.

I picked up a cam sensor shield from Kozmic and clocked the turbo just a bit back towards the FW and it seems like it's running well now.

Sorry I didn't post back sooner -- it's been a crazy month!
