    so after the last couple of days my car playing up on idle and when accelerating its starting to missfire which points toward coils/harness/plugs, plugs are bosch super 4's few months old wire and plugs look original, i have bolt down coils and a friend with a 1.8t ibiza has push downs, can i use his coils in my block to test them, he also has 1 new one spare so can i run 1 push down 3 bolt down to see if my coils are at fault? can faulty coils cause bad idle? thanks

    I believe you can use push downs if you have bolt downs, it's not ideal but you can mix and match, and a faulty coil will cause bad idle.

    I melted a Bosch super 4 plug in my car after his a couple of months, a few others have has issues with the plugs before so double check they are ok. I only use NGK from now on.

    if its the plugs or a plug at fault would it be constant miss fire as it seems mines random?

    Mine seemed to drive ok until I gave it some stick. Would be worth checking them.
