    Default Vs misfire on angle

    Hey guys just noticed my car has a major misfire when the car is on an angle, when it's on flat ground it will run perfectly fine but when it's on a slope it won't run right,
    I just did plugs and leads but what else could it be??

    When you say on a slope, is that uphill, downhill, left or right or all of these? Also try a fault code check: Checking error codes VR/VS (Revised)

    Have you checked that the plug leads are fully pressed onto the spark plugs? Also, it is possible to damage the leads if they are not carefully pulled off the spark plugs. You could check the continuity of the leads with an ohm meter. Gregory's states the following limits for high tension lead resistance:
    No. 1, 3 and 5 cylinders: Less than 17,000 ohms
    No. 2, 4 and 6 cylinders: Less than 25,000 ohms

    Kind of sounds like low fuel / dodgy fuel pump to me. .... I can't see how leads would be that sensitive to inclines.

    Greenacc could be right.
    How much fuel is in the tank? Does the car do it when full?

    Don't buy a Goss brand pump as they are not much good!.....otherwise are you 100% sure the pump was the problem and not the wiring to it or the fuel pickup blocked in the tank?
