judders

  1. Car judders but not coil pack related!!

    I get the same judder as a coilpack blown but no missfires or codes or Check Engine light. I was told it's most likely spark plug failure :confused: Denso IK22 . 15000 km. Any suggestions? Thanks

    judders or loads of small misfires when turbo comes in!!

    as above this has got gradually worse. it started off juddering or possibly misfiring at 15+ psi now it has ended up 0+ psi and it does it! any ideas. cheers in advance.
