Before you go tearing into the internals of the engine, why not pull the serpentine belt and check the rotation of the pulleys. You can also consider the alternator. Those tend to go out around 100k -120k.

You can also check the PCV line. Some FF's have reported it to be split causing idle and running problems. It is not easy to reach. It is located between the intake manifold and the engine block. The PCV valve itself is up above where the oil filter is in a black box. Follow the short, 6" tube from that black box to the intake manifold. That's the PCV line. You should be able to grab it and tell if it is split.

Tumble flaps are the cause of the "valve noise" sound, and probably not much else. Mine have been bad since around 100k, and I now have 150k.

You should really consider the KISS theory before you end up either taking apart a perfectly good engine and screwing it up, or spending a lot of money on something you don't need.

After I get the new coil boots on I was going to replace serpentine belt. Alternator could be part of issues, at times car does "dim down" at low rpm, and didn't used to. I thought I checked PCV hose, but I may have been grabbing on the wrong one. I'll check again tonight. Thanks for the suggestions.

New boots and ap104 gapped at .55 seemed to help mpg but not the stutter under load. Seems worse when car warms up. Almost nonexistent when first started this morning. Haven't gotten around to look further into the pcv yet due to busy schedule (and home repairs)
Thanks for the tips

Update. Pcv hose fine. Turns out was bad axle and passenger engine mount. Runs like new now. Thanks for suggestions!
