My wife's Taurus is acting up. It is a 2005 3.0 with 90000 miles on it. I searched the internet and figured it was the cam synchronizer and we replaced it. It will still kinda buck or hesitate when shifting into second gear. What else could it be. I have a feeling it is something simple. HelP!!

Get a code reading. No harm in cleaning IAC and throttle body either,

I hope you marked the position of that synchronizer very carefully before removing the old one and installed the new one in the exact same position..

Mechanic did the job, and am assuming it was done correctly. How can I be sure?

IAC is in the intake air to measure the flow of air going in as part of several things that the engine's computer factors in to make exacting adjustments for maximum performance and drivability w least emissions of course too - more troubles with idle if bad/dirty.
Exactly the acryonym - IAC = Idle Air Controller - dang, we/I get so used to acronyms (should speak for myself) such that forget exactly what it is spelled out,

The IAC is not a sensor, it's an actuator. It doesn't feed info, it takes commands from the PCM to allow more or less air into the system to adjust idle speed.

Great - I stand corrected on exact use/purpose. I know they can mess up idle,

#6 cylinder is misfiring with first code and next is noticing it runs rough at start up so chase down spark and fuel delivery to that cylinder,

Would replacing the crankshaft sensor help?

Doubt that would pick on one cylinder. Check or swap plug with another or at least check that one with one that isn't misfiring.
Some tools to have is a noid light for fuel delivery, and a spark tester which can show how far the spark can jump a gap. You may find, hear or see spark jumping out in the wrong place. Those items are not very expensive as things go,

You still haven't accurately identified which motor you have because they are all 3.0 in that car. The 8th digit of the VIN will determine that.
Assuming you have the OHV (Vin U), it is a "Coil on Plug" system and you likely have a weak coil on that cylinder. At that mileage you should be replacing the #6 coil and all of the spark plugs.

Eight digit is a "U". But what is a the coil plug you mention? Does each spark plug have one? It isn't the coil pack, the one in front where all the wires connect? Excuse my ignorance but I am not too mechanically inclined.

It appears that they made both types that year. I was assuming you had a separate coil on top of each plug with no plug wires but if you have plug wires, then you have a coil pack system. If that's the case, then I would recommend plugs and wires.
