Thank you for the info,
I had a look at the plugs today and they are single point platinum set to almost 0.8mm so ive closed them to 0.6mm after a test drive it still drove like a bag of spanners. the fuel gauge just reads one red dot (always 1 red do even with a full tank)
I ran vida and cleared all the error codes. test drive and checked it with vida again and all i'm getting is the CCM fault.
After searching the internet today I found a interesting article explaining the fault diagnostic of a 2.9L XC90 that had long term trim fault codes and it went into details about the 'Y' shaped charge pipe having a leak problem especially at the single end that connects to the rubber pipe.
I'm going to try a leak test tomorrow (and no I don't mean leak and potato soup!!!)
I'll take some pictures of the LPG system as well
Which one of the spark plugs do you prefer classicswede?
