The old girl let off a massive backfire tonight on the way home from the shops...
...yes I do mean the car... doing about 3000rpm, moderate acceleration, on LPG. Anyway after I reflexively lifted off and switched back to petrol, it's dropped a cylinder or 2 and is making like a chaffcutter. Too dark to see anything obviously amiss, the plug boots are all firmly on the sparkplugs, but there seems to be some side-to-side movement in plugs 3 & 4. Had to ease home at around 1600rpm, over that it started making metallic noises. More when I get a chance to look in daylight. Inclined to think the backfire was a symptom rather than the cause of the missing, just seems odd that such a serious miss could suddenly start rather than gradually develop.
