V6 popping and missing firing
I have a 156 that has a gas conversion. Whilst it warms up on petrol it miss-fires and pops, but when it goes over to gas it's fine. It also has the motor system falure notice up.
Yesterday I thought I'd try and give it a clear out on petrol on a bit of dual carrage way so switched it back to petrol, dropped it down couple of gears and floored it. It failed to pull at all and motor system falure notice repeatedly kept sounding for several seconds after I lifted my foot.
Is this possible symptoms of the air mass meter? I know it's nothing mechanical as it runs fine on gas.
Any help would be gratefully received,
