Does this look like a bad mount? All I see is a little cracking in the rubber but I am chasing an intermittent shake that I feel at idle which the rpms are stable at the time I feel the shake.

Check for a wobble with your harmonic balancer

Ok I will take a video....wouldn't a bad harmonic balancer shake all the time though and not intermittently?

I replaced plugs wires and ignition coil. I wonder if I am having an intermittent issue with the spark signal either from the crankshaft sensor or the wiring back to the ignition coil itself.

How important is it that I use motorcraft plugs? I changed plugs but didn't use motorcraft

Hopefully you used copper core, but as long as you put the listed plugs you should be good.

Dave,

It seems like you've recently posted four threads on this shake / idle problem:
Chicken or the egg? Maf live data
Slight shake at idle
Live mode 6 misfire data?
Does this look like a bad engine mount?

Just a recommendation, perhaps just stick with one thread on the problem, and rule out the things that you've checked and folks have helped you to eliminate off of the list. You might get some better, more consistent help that way rather than scattered opinions on each topic (not judging any of the responses to these).

-Jim
