Have they checked the gas mixtures, if way to lean they will over heat.

OK ill ask - cheers.
Is there supposed to be a catalytic converter on Dedicated LP gas models? See below?
The mechanics are saying this ute has one and that it could be shot so the motor is running "constipated " I'm no mechanic - obviously - but I thought that LPG was pretty clean burning and all you got as a by-product of LPG combustion was water? So why the need for a cat/.

Thanks for your answer.
The head has been lifted - badly burnt valve on # 6 cylinder - other valves on the way out.
Also evidence of small holes in diaphragms on lpg mixer thingy. ( Green deposits - anti freeze - on plugs )

No mention of a misfire in the first question, it would have been running on 5 cyl.

That was our thoughts as well but no. It seams that LPG is more forgiving than other forms of fuel.
