Engine Miss Under Load

[Lost_Pete]

The V6 had a odd miss usually under load and more so when it was hot.

Tracked it down to a bad coil pack, but decided to change all three plus leads and plugs. (Plug #1 was a different colour) Runs great now.

The bad coil pack didn't show up using some of the tips on the forum such as being hotter than normal.

Just thought I'd like to share this in case anyone is having a similiar problem.

Ive also seen a couple of them show to be ok, with their multimeter readings all within spec,but they were still faulty and breaking down under load,causing a misfire.So even testing them with a multimeter is no sure way to tell if they are good either.I keep a spare new coil to test them.
