    Question Fault Code P0301 - Cylinder 1 Misfire

    Hi Guys,

    Just want a bit of clarification / help here.

    My EML came on today after a short drive in the cold (1°C), my incar PC flagged it as Code "P0301 - Cylinder 1 Misfire Detected"

    Now my first idea was get the coilpack out give it a check over and some WD40, which i have done and has made no difference.

    Should I be buying new plugs now? and looking to a new coilpack if that fails? I don't want to head down a route if there is something that could be causing this misfire e.g. coolant temp stat (which incidentally is new as this failed a month back)

    Just to reitterate - I only have the 1 fault code.

    Thanks Guys,

    J

    Id be lookin at the cheapest component first

    so check the plug in pot 1 and even replace it with another one and see how things run - check the codes again - if its still a fault on the same piston then more than likely its the good ol coil pack

    Still says P0301 ... I'm not being dumb and Cylinder 1 is on the left as you look at the car?

    New bosh coilpack from Halfrauds £45.64 - does that sounds about right? Is it worth getting a price from VX?
