Hi all, i just replaced my ecu to a Z4 and have devolped a s misfire, i've changed 3 out of 4 coils that were split and all spark plugs but it's still there but only every now again when on boost I bought the coils second hand and i think it's them playing up?

Any ideas?

Also where can i get new coils form and prices.

Many thanks

Matt
