Hello everyone,

So as the title states, I have random misfire CEL that comes and goes and the car runs fine but feels weird in the 1,000-2,000 RPM range. So gas mileage is obviously worse right now but the car runs and pulls just fine above 2,000 RPM.

After reading lots of posts on the internet I have it narrowed down to being the "flaps" in the Intake Manifold, which is stock.

I just called my local Ford dealer and they are saying the labor costs would be $1k+ to replace the "runner control something" which I assume is the Charge Motion Valve piece that is for sure cracked or broken.

What I am trying to figure out, is if this job should be cheaper if I buy the new version of the intake manifold (fr3z-9424-n) and do it myself or find someone willing to do it for less? Or just live with it until I decide to Supercharge the car...

Let me know if you have an insight on this issue or anything related to it.

Thank you!
