Hi all, not been on here for a long while but I still have my QP. It has sat around a lot over the past couple of years while life got in the way. Often on a trickle charger and started up and moved occasionally. REcently I've decided to get my **** in gear, get it recommissioned, use it for a last hurrah then sell it.
So, it went off to my specialist (Lotus mainly but has worked on Maseratis and also has access to the Maserati scanner equipment via a contact at the nearby dealer). There a load of work got it back up and together generally and sorted a couple of issues such as one of the speed sensors going duff. All good.
I got it back and all was well with the world until a couple of days later it flashed the engine light at me for a few seconds then stopped and all seemed fine again. I put this down to "italian" and left it at that. It's since started doing that though a lot, basically any time you give it anything more than a tickle on the throttle. Basically there's a misfire and you can hear just that while idling. I tried my scanner on it and pulled off a pending code telling me the misfire was on Cylinder 3. Hoping and praying for the obvious to be the cause I swapped the coil on that cylinder for a new one. Same issue, bugger.
So, any ideas on where we can start to look next? It'll be going back in the new year to be scanned properly etc again but I am just wondering if anyone has any other ideas in the meantime.
The only other alarming thing it did during this sequence was that after changing the coil I had it idling outside for a while to get some temp in it and while I went and got keys and wallet etc to take it out for a short test drive. While doing that it cut out and completely and utterly died. Total electrical blackout. During the coil swap I had disconnected the battery so I first checked that in case I hadn't tightened it well enough. Seemed fine but I disconnected and reconnected it again and it came back to life. Misfire and flashing light when accelerating aside it seemed happy on the short drive but back on the drive it cut again after idling for a while. This time though while the engine cut the electrics remained on.
