Rev 1 Turbo running very rich

Post by Mossy1664 »

Hey all,

New owner of a Mk2 Rev1 Turbo. And here I am already seeking the knowledge of this forum!

I bought it as a bit of a project, and have noticed it is running very rich, with a bit of a misfire.

It has a MS2 ECU on it, which I plugged into my laptop. Everything seems ok, except the fuel air ratio was stuck reading 16.9. I’ll assume this is an O2/Lambda sensor error? Could this be causing a misfire, slightly off idle, black exhaust tips and running rich?

I do have a few other small issues, like fuel cut off on full boost periodically, but that can wait until I’ve fixed this one first.

I added the datalog file here if anyone knows what they're looking at. I'm still learning this so still in the process of understanding all the readings.

Thanks in advance everyone. Loving the MR already.
