    Intermittent stutter

    Got a intermittent stutter/misfire problem, not sure what it could be. Plugs have been changed, service only just done, its been mapped this year so all in good health. However ever now and again if I go for a quick launch, so build up the revs and go for it in first, the engine seem to bog...

    Motor intermittent jerks

    My motor suddenly developed intermittent jerks on acceleration and becoming worse by the day. :rant: This usually happens after cold starts. However, after 5 mins of up to operating temp, the motor is ok. Could anyone help me to understand whats going on? Is it plugs or coil packs or something...
