Ok, it would seem that I have a minor fuelling problem all of the sudden.
Rode home from work last night and the motor was running below 80 deg.C and wasn't idling to nicely.
Today it is running colder, in the 60's. By the time I got home it would hardly run, plugs probably deteriating rapidly, and the fuel light came on after only 138k's.
I haven't attacked it yet but thought I might get a few ideas first or during.
I'm thinking stuck injector or maybe crank or cam sensor, I'm about to look for codes now.
I have doubled this post up in the other forum. I want to get this sorted quickly and not stuff around.
