when you fix the problem, the ight will go off. Find out why its on, have the engine computer scanned for a trouble code and that will point to the direction of the problem.

p0606 is a generic code for a prob with the powertrain controle module and/or a power supply issue the p2 codes are for body codes check the the pcm for water ingress and corroded connectors

replace all the ignition coils, this vehicle is known for ignition coil failure. Typical symtoms include: jerks when accellerating, jerks on light-heavy loads, misfire, stalls, check engine light. These coils usually last up to 80k miles.

Sounds like the EGR Valve, Get the check engine light checked at your local garage or autozone or advance auto.

If there is an Auto Zone around your area, have the truck scanned for the DTC codes which is causing your idle problem. There are to many things that can cause your trucks idle to be rough. Once you have it scanned, we can address the issue and have your truck running 100% again. Auto Zone scan free of charge and can give you the step by step instructions to repairing and replacing the parts needed. Good luck and keep me posted, be glad to help. 

I carried it to a Lincoln dealer, it in the shop now.

you should have the check engine code scanned at a garage,
