    Surging and miss firing after MOT.

    My E350 was in for its MOT on Tuesday, which it passed. Since then though it's been surging and miss firing particularly when the engine is cold. I realise it could be a coincidence, but is there anything that the MOT could have done to cause this sort of issue? As prior to the test it was fine.

    How to turn engine over without starting (firing)

    Hi My c43 has been sitting for 6months now unstarted in storage Is there a way I can disconnect the spark to stop engine firing up , to allow a few cranks to get oil flowing / build oil pressure ? My first thoughts were to remove the fuel pump fuse ? Any help appreciated Lenny

    Hi all, I wonder if anybody knows the firing order on a 112, 2400cc V6 engine. Mine has developed rough idling and I've been told that cylinders two and five are misfiring. The plugs have been replaced but this had made no difference. My specialist says that the coils on these two...

    W124 260E 1990 Not firing!!!

    I'm at a total loss. My 260E has died. She turns over strong and there's definately voltage to the HT leads (ran a strobe timer.) I've changed Fuel Pump Relay as the (clever) AA man said it will be that. All the fuses are fine. I can hear the fuel pump start and other bits and pieces spring...
