check engine light came on today, took it to autozone and got the P0307 code...ok...i've searched and found out this could be caused by several different things. my question is how do i diagnose what actually IS causing this? i don't really want to take it to the dealer to diagnose it (trust issues ) any help would be greatly appreciated. thanx.

If I were a betting man I would put all my money on the coilpack for that cylinder. Your valve cover seal is more than likely leaking oil into your spark plug well and shorting out the coil pack. It already has or WILL happen to all lincoln ls's that have the old style seals in them. New coil packs are $35.00 from autozone and your gaskel seal kit is $44.00 dollars from your local stealership
And if it has been raining don't be surprised if you have water in there and not oil but it could be just a bad coil if you've never changed any before
Is your car still under warranty - if so let the dealer handle it

Unless he has an extended warranty, his car's warranty is long gone.
4 Years / 50K miles, whichever comes first.
