what engine do you have, could be moisture in the dist cap, a worn lead, possibly a blocked fuel filter or an ecu problem.

My dci 65 has started missfiring aswell now !!

Car is doing my head in,

Im running my sub atm and according to the mechanic it doesnt startup properly because the subs using up too much power?

Anyone else had any problems like this?

Coils are a possibility.

As for misfire on a dci its not that otherwsie you'd realy know about it best take a dci to soeone with the correct equipemtn might be a TDC sensor or if its got a few miles on it injectors are leaking but you can often tell that as the engine smooky and less power.
