    Torque for Coil Packs, Spark Plugs & Head Cover Bolts?

    I replaced all 8 of my Coil Packs this weekend with Denso packs & Denso Iridium Spark Plugs. When reading this forum I thought that I found the right torque values but, I am pretty sure that the Coil Pack bolts torque was off because I snapped the very first one off. Luckily I was able to get...

    Replace all ignition coils and spark plugs simultaneously?

The passenger's side cylinders (2,4,6,8) were replaced 6 months ago with non-OEM aftermarkets. Today I just had the 3rd of 4 non-OEM coils fail. I clearly...

    I think it was time.

    I had been experiencing some shuddering during acceleration lately, and read that it could be caused by bad spark plugs/wires/distributor cap, so I decided to pull the old plugs and put some new ones in.
