Yea, thanks for asking. We had strong winds and lots of rain for about 24 hours. Lost some shingles, the fence will need repair, and the yard is still under water, but other than that we did well. Only lost power for about 10 minutes. Gustav was worse.

Oh, and the dog escaped during the brunt of it. I had zero shudder issues while driving around in the middle of the hurricane.

Will be heading out on a short road trip finally. Hopefully will see if the shudder is gone or not.

Update: 150 km trip and not a single shudder on any if the hills that it used to do it on.
Time will tell.

You guys have me wondering now.... I guess I need to pull my plugs and check.

Plug gap is extremely important for optimal performance. Before now all my rides have been NA and I ran the largest gap for the biggest flame front. From what I've read we're shooting for 32-34 for the Ecoboost, is that right? Does anyone know when the forced induction will start to blow the flame out?

FTR: Autolite plugs are great bang-for-the-buck. I consider plugs a "wear item" and typically check/change them every 20k miles, or so in cars; more often in the bikes. NGK makes a fine plug, but they are often cost-prohibitive.

Stock recommended is .035. All the guys with tunes are going down to .030.
I put mine at .034

That gives us some hope!

My wife bought a 2012 Fiesta and it's got a bit of a shudder as well. Guess what I'll be checking!!
