  • 3B Misfire!! SOLVED

    I had this damn misfire that was driving me nuts, so i decided to actually take a look at what might be causing it, as one morning last week the car was stalling when cold and being a right ****** to restart. So I sprayed under the bonnet a light mist of water and could see the spark arcing over the top of the coil.

    Luckily I had one 'in stock' thanks to Steve H for that!!

    This stopped the car from stallling when cold/damp, but i still had a crappy misfire at the top end. With the cost of the HT leads having gone up recently i decided to take a risk and buy a set of 7A leads from GSF. They do just about fit, but i now cant refit the '20V Turbo' cover. Nevermind!!

    The car now doesnt misfire and idles perfectly, as before it was lumpy at idle, i fitted a set of spark plugs whilst i was there too.

    The reason for my 4 cylinder moments was the ******ed no. 5 lead, the wire cam eout of the boot!! Not bad for 163k miles!!!

        Glad you got it sorted Tom. That misfire was savage. Losing one cylinder at WOT on your car seemed to make a lot of difference to the acceleration. I'm not sure how your head didn't get thrown through the windscreen!
