Ok, I thought I'd run this one past ou all..
Yes its my bloody camper, wot I write about last year as having crap fuel consuimption..well its always sounded odd when cold, but in the current cold weather it got much worse, to the point where it became obvious it was actually only firing on three cylinders..and the occasional massive BOOM from the exhaust and a stink of raw petrol confirmed that unburnt fuel was collecting in there.
Ive got a set of new plugs for it, but I pulled one out today and there was no sign of excessive wear or age..this camper was bought second hand a year and a half ago, and its always been a bit juicy and gutless..
So I will try those tomorrow, but my deep paranoid suspicion is that there is more to it than that. I would have aid 'coil' but these things aren't that simple are they?
Anyone know their way round these?
It's a Boxer chassis with a 2 litre injected petrol. About 97/98 vintage.
Am I right in saying that plugs, leads and something called a 'coil pack' are the main elements of the ignition.. One of those components is breaking down under high voltages..intermittently. By dint of using high RPM and getting the battery voltage way up, after a couple of hours I did manage to get it into 5th gear and over 60mph..the usual stuff..light throttle high RPM is good..pulling from low on a rich mixture it misfires totally on one, and at moderate revs in low gears, I could feel the 4th cylinder coming in and going out as it juddered..
Anyway, any feedback, or humorous stories welcome.
