Looks like your engine is running rich, enough so that it's past a pre-set limit to warn you that something is wrong.
It could be due to a number of things. Here's a few that the Bentley lists.
- bad MAF
- bad O2 sensor
- fuel injector(s) leaking
- fuel pressure too high
- evaporative emission (EVAP) canister purge regulator valve -N80- permanently open.
My guess is it's one of the first two.
