I bought my third 4/4 ( 2012 ) last December and unfortunately due to ongoing horrendous weather I didn't get the opportunity to drive it until last weekend ( Easter ) - I did about 150 miles between Good Friday and Easter Monday and absolutely loved it.

Unfortunately on Easter Monday, it started to run "rough" , and seemed to be "missing" and sounding like it was running on three cylinders. at one stage I was beginning to wonder if I'd actually make it home, fortunately I managed to make it, parked up and five minutes later tried to turn it on again and it refused to start ! I left it for half an hour, tried again and it started first time, albeit running very rough. Subsequently the engine management light came on as I drove it into my garage and parked it up for the week.

Returning to the car today, it started first time and the engine management light came on immediately, it ticks over, albeit very rough.

When I bought the car ( from a non Morgan dealer ) I immediately had it taken to a Morgan specialist who went completely through the car, replaced all fluids, changed the brakes, brake fluid, oil, timing belt, upgraded the suspension, etc, etc and did a brilliant job.

I live in Yorkshire which is approx four hours from them so difficult to get it back for investigation.

In short, has anyone experienced this with their 4/4 or have any ideas as to what the cause may be ?

Any help would be greatly appreciated.

Thanks

This, plus: When was the last time you put fuel in it? Was it sat for 4 months with aging fuel? If you don't get anywhere with the faults codes (I bet it will be a P03xx misfire) then I'd try draining as much of the old fuel out as you can, bunging in a fresh tank of E5 and taking it for an Italian tune up, especially if it's a P0300 random misfire.

If it's a specific cylinder indicated (P0301 is a misfire on cylinder 1 etc) then coil packs and plugs would be next on my list to check.
