Lincoln Repair Questions? Ask a Mechanic for Answers ASAP
Hi, I’m Chris. Welcome and thanks for asking your question!
Step one is to remove the air intake tube from the throttle body. Get a helper to turn the key to run, engine not running, and hold the throttle down 100%. Now you need to clean the throttle plate and throttle body with a tooth brush and spray brake cleaner. Now reassemble. Disconnect the battery and wait 10 minutes and reconnect, only remove the negative. The alarm may sound on re-connection. Now enter the vehicle and start it. Take it easy for the next 50 miles. Then see if the concerns come back. if they do then you need to replace the throttle body for internal wear in the throttle motor and not a concern with carbon on the throttle plate.

I am sorry my diagnosis was wrong, I can submit a refund if you would like, I do not mind. I would still like to keep helping if you do not mind. This has to mean there is a wire short or a fault within the PCM now. You need to complete the below tests.
I just wanted to let you know that I resolved the issue with my car today. I replaced all eight plugs and COP and the problem is gone. Car runs great now, at least for the current time. Replacing the plugs and COPs was much less expensive than replacing the throttle body. I am told that bad COPs can cause a variety of false codes to be thrown.
You are correct, a bad COP can cause a frequency signal that confuses the cars computer. Thanks for the input and I am glad you have gotten it resolved.
