There's two installers in Sheff that i've had conversations with which have clouded my judgement as they stated that gas "could not" affect petrol fuel trim. I was confident all along thats what was happening due to the "reset" solving the issue short term, that's why i asked all the basic questions just to put my mind at rest. Do you have the contact details for that gas installer, i'm willing to travel to get good honest service. Thanks Guys for all your input. Jim
