2006 Mountaineer firing order & cylinder misfire.

[chilgun]

I have a 2006 mountaneer which seams to miss fire when I am around 50mph. This cause me to repair my transmission, which by the way cost me $3400 about two weeks ago. Again, the same problem is happening and I do believe it is the coil or something that is causing this. Can anyone help?

Welcome to this forum! I've moved your thread into the stock 2006-2010 section. Here's a link with the firing order information: http://wiki.answers.com/Q/What_is_the_firing_order_on_a_4.6L_Ford_engine. Here's the firing order: 4.6 L V8 firing order is: 1-3-7-2-6-5-4-8.

I had a problem with mine misfiring once and I took it in but they said the coils looked fine. Maybe it's your spark plugs?

Been here done this...

Spark plugs are the #1 potential cause here ... IF you allow this to go too far, you will then lose a coil on the bad plug(s). I had one plug/coil under my extended warranty but they warned me the others were going (plugs - then to eventual coils).

Make sure you go thru Ford or get Motorcraft Platinum plugs and swap ALL of them out.

(thankfully I have a Ford truck mechanic friend who does work for me on the side and saved me a bunch of $$ on this).
