FICM? Sputtering power.

I have an 06 and have readings on my FICM voltage of 36-39v at start up and 48v after it warms up on acceleration. My question is, would my FICM with the low voltage at start up contribute to my low, sputtering power until it is up to operating temp? And with the low voltage at start up on the FICM should i replace or repair it? Thanks for any info. Also if the FICM isn't the problem with the sputtering power what might that be caused by? My ford dealer said it's my fuel. I put injector cleaner/fuel conditioner in every other tank.

The FICM voltage should never drop that low, I think 45v is the lowest you should ever see, so that is a problem that you should address.

How you go about it is up to you, if you feel comfortable soldering very small components then you might want to give a try, but most FICM repair places won't work on it after it's been messed with.
There are several FICM repair places to choose from.

Some guys opt to just go with the Swamps FICM (either 48v or 58v) which has many of the electrical components upgraded.

Yes your FICM is the problem. The 58v Swamps upgrade is a good idea or if you just want it repaired.
