    Missfire sounding like a scooby!

    So the car's been running fine, bar a smoke issue that I'm getting to the bottom of.

    Decided to do a compression test last night, all four cylinders between 175-178 psi which im really happy with.

    But... after putting it all back together, and taking it for a rip...under full load it missfired like mad, engine management light flashed then stayed on and it sounded like a scooby!

    It would continue to sound like a scooby(bad missfire) until I'd turn the car off and on again.

    But any signs of boost it starts the process again

    I re-assembled everything as It should be?!

    maybe you didnt put the plugs back in properly?
    id tak them all out and refit them carefully.
    failing that get a new coilpack as they seem to fail rather quickly on these things

    misfire is generally knackered coilpack, but as said refit plugs and test.
    any codes? lot of times knackered coilpack doesnt show codes though

    I put the plugs back in fine, all as tight as each other.

    I guess it could be the coilpack?! Is it a Bosch unit? (will get it somewhere other than Vaux if so)

    mine does that if i give it some beans before the cars upto temp (i know thats bad) and then if i check it shows the fault code for engine overspeed condition (0219). normally happens to me in 3rd. but engine off and on always gets rid of the light and sorts it out
