engine misfire
if all is fine when warm...then ecu is on closed loop and all sensors are responding fine....if lambdas are reading lean fuel....then it means either lack of fuel or too much air....in which case ecu would compensate by introducing more fuel...thus the poor fuel economy....
if timing was out then u would get misfire at all times not when cold.... judging by the condition of the discs when u bought it the car has been standing for a bit ...my first act would be clean the o2 sensors (or replace em wit the s8 ones) , maf... remember when ur running lpg...it is tough on components...and can sometimes leave a glazed coating if not fully combusted.... my guess is the one of the pre-cat o2 sensors is duff....

It's vibrating worse now when it's hot and when cold. Very noticeable, a little lumpy when accelerating at low revs to. On both petrol and LPG. Got 200 miles on LPG and not 230 as usual.
My brother in law vag commd it for me as I was tired after coming back from Germany and he said one of the pre cat lambdas was reading out of it's values, but no engine management light. Can you guys please suggest something as I just cannot do without a car. I'm going to see James (mkoneman) on the weekend to see if he can find anything but any suggestions till then would be greatly received.

Just a coil pack that was on its way out.
 Had the cambelt re done and fitted correctly too, as it had been Tipex'd on by the previous owner, I hate botches on cars like these.
