It's been a second time that my car (cold engine) went crazy, throwing like it wasn't running on one cylinder. I figure it can be fault of either spark plugs, ignition coils (hope not!) or ignition wires. I'll start with changing spark plugs since i got no idea of when it could have been changed. What kind of spark plugs do you recomend for M42? I heard 4-electrode are good ones.
Thanks

Hi,
i've bought NGK BKR6EQUP today. They were quite expensive but should be real good.
Also Bosch FGR7DQP are excellent for M42.
