Mick,
Fuel/air ratio is controlled by the ECU by way of the fuel injection
system. When it's out of whack and there is to much fuel......Black
Smoke, at least under certain conditions. But white smoke....? Thats
oil, my friend, and that is worrisome. Says something is wearing. Rings,
guides, etc. In my case I got white smoke and had a piston failure.
Burned right through. I had white smoke for a while but didn't
understand the message .... that failure was imminent.
With white smoke, I suggest you have a compression test done by a
competent mechanic. He should be able to give you a reasonable
diagnosis.
