    could be a miss caused by dodgy coil pack or injector connectors - check those are ok & no signs of corrosion. replace or clean as ness

     

    have you checked your plugs?

     

    check your O2 sensors, either with a conzult or putting the ECU in diag mode 2

     

    clean connectors to PTU
