#6 misfire so i changed plugs and kept getting number 6 misfire, changed the throttle sensor kept getting #6 misfire, changed coil and misfire went away. now im getting a P0017 code is that the camshaft sensor or crankshaft sensor

hey thanks for bringing me up to speed. ive been working on many other problems but with your great explanation i remember.
we need to check the compression on that cyl. and compare it to the compression on 2 other cylinders your choice.
but before you do this get a can of carb cleaner . and with the car idling spray around the intake manifold in the area of #6 cyl. what we are looking for is a small vacuum leak that would also act like this. with the engine idling and spraying around the intake the engines idle sould not change and if it does when you spray you have an intake leaking.
let me know how it turns out.
later

Yes start with the coil pak. There are three located on the front of the engine on the pass side, you probably know this. They are marked as to which cylinder each wire goes to, disconnect the wire for #5 cylinder, and if the engine misfire does NOT change, it is more than likely that Coil Pak. Replace it, and use dilectric grease on the two contacts when reinstalling it. Now, I have stumbled on this issue many times and if that does not cure the issue (I think it will), the coil module below the coil pack is probably bad...To remove this module, remove the coil paks, the electrical connector in front (has bolt holding it in) and I remember one bolt holding the module to the aluminum bracket.
Again, to be sure you can switch coil paks around to make sure it is a coil pak. When you switch the bad with a good, the misfire will follow the coil pak, if it does not it is the module.]
Hope this helps.

What vehicle?
Spark plugs never misfire, by design, Wear yes,that stresses the
ignition modules
If you have a coil, that is for all cylinders,the others fire okey !
We need your year,engine, V6, V8, etc, to help
You never change parts to solve any issue
That is called wishing,hoping,pushing,poking,
What code # did you get PO306?
