Question about Cars & Trucks
That is way too much to have to do on a 2006 already
I would look at fuel trim at idle & on a road test,also cylinder
misfire counts in Mode #06 on the road
That requires a professional scan tool to look at data
Were the upstream O2 Sensors done at 100,000 miles?
Fuel Pressure --checked at motor?
I would have smoke tested the intake after the work that was done,
also smoke the Evap System from purge valve back & gas cap
forward,for leaks,press or vacuum.
Exhaust leaks-again smoke it
Check injectors with a scope & ignition cop coils
You need the OEM Brand & part # spark plugs as well
Just attention to small details & you will find the issue
Egr System !!!
Sort of guessing at injectors sticking or dirty,the scope
trace will give you a hump when they stick
I would try Mobil 1 5W-20 as well
That is what my Lincoln LS has to use
Can't hurt during the winter
I don't know if you have VVT Actuators on the cams or not,
thus the thinner oil & add some Marvel Mystery Oil
I don't care for any additives, but that never hurt any vehicle
I have had for the last 45 years

Have you heard of Noid lights? You unplug the fuel injector and plug these in and they will light up if the injector is getting power. This might give you a better hint. There are also lights that go inbetween the spark plug and wire. Between these two items you may be able to narrow down the problem to a specific system. I believe that your car has a coil pack. Some of these engines have problems with the crank trigger. I believe it is located on the back side of the motor. If you decide to change it, be careful. I have heard of them breaking into two pieces and becoming a big problem.

Have you "reset" the computer on the car. When parts are replaced, the comp continues to run the vehicle on all the old settings which can drive you nuts because nothing you do will fix a problem. Usually, taking both battery cables off and waiting for 15 minutes will reset the computer. If this does not do it, then ask a dealer how to reset yours.
