Why did you have the MOT emissions on LPG when Petrol would be truer condition.Get the petrol checked first as this maybe giving false reading for LPG running.

hi, if the vehicle is running on lpg when arriving for mot it legally has to be tested on lpg i.e. emissions test has to be set on l.p.g. test !!!!!!! if you have been running for 2 years then just buy new filter & sray clean the maf ( not with wd40 ) Any good electrical spray ok .
I presume its a 4.6 2000 era ????, anyway its passed so you got plenty time to check it out , enjoy cheers mozz

Should be clean on LPG. Good call on the MAF.

Spark plugs take a bit of a hammering with LPG too.
