Looking for a bit of a pointer in the right direction please….
My 2000 Thor has started running very poor on petrol particularly when cold but also when hot too. It can be almost cutting out when cold and no response to throttle now and then, I think I can hear popping fro exhaust when it’s playing up too.
When hot it’s sounding like it’s misfiring but nanocom says not, it’s running “lumpy”. The car shakes gently.
It runs perfectly on LPG. It also runs perfectly when I reset engine adaptations.
I get p0172 bank 1 mixture adaptation factor few signal too low and p0175 bank 2 as well.
Clearing makes no difference.
Today though resetting adaptations has made no difference….
I’ve changed the MAF for a new genuine Bosch one. Initially I thought it fixed it as it was ok for a while.
I also put a bottle of injector cleaner thru.
It has 2 new coil packs, new leads, new plugs, fresh oil, new air filter,
Where shall I look next? I have nanocom but don’t really understand the numbers!
