Welcome to the forum!

Code P0316 is not a cylinder #1 misfire code, it is a code for "Misfire occurred in the first 1000 Engine Revolutions." P0356 is the "Ignition Coil F Primary/Secondary Circuit Malfunction." Ignition Coil F I believe is coil number 6.

Code 2104 is not a misfire code, but rather "Throttle Actuator Control System - Forced idle." The P2107 code actually is "Throttle Actuator Control Motor Processor." code P2110 is "Throttle Actuator Control System - Forced Limited RPM" and code 2112 is "Throttle Actuator Control Ssytem - Stuck closed." These codes would typically indicate either a wiring issue or hardware issue with the Electronic Throttle Body. They could also be due to a damaged PCM.

However, if you were to search the forum for details on misfires for the 2003 and newer LS, you'd find others reporting that misfires can cause throttle body codes, likely due to ignition noise getting on the electronic throttle body wires.

So, I'd suggest you start by fixing the misfire codes and that will probably take care of the throttle body related codes as well. Additionally, there are things to look for when pulling the coils. While these common issues are not so common with the 2003 and newer models, you still need to check them. I'll let you use the very helpful "Search this forum" feature from the Lincoln LS forum main page to find out what items to look for.

Is the LS you're working on a V6 or V8?

Thank you,
HOW do I get out of Limp (ETC) mode?

I had read the TB threads and information on that.

I find now that friend decided to pressure wash the engine,
just before this happened. So, maybe that has something to do with it.

I'll keep searching also, also of information to digest.

You get out of limp home mode by fixing the problem.

While pressure washing the engine, there's a good chance water was forced down the spark plug wells, causing the misfires. You didn't mention if this is a V6 or V8, so pulling all coils and cleaning out the plug wells, inspecting for oil or just water may or may not be easy.

If the V6, thump the owner on the head for pressure washing the engine and suggest they NEVER do that. Pressure washing any engine is not a good idea.

There are posts on this forum related to water getting into the spark plug wells. If the V8, you'll want to be sure to apply sealer to the appearance cover when reinstalling.

yes, sure will get water in wells on v6, finally figured that out, just from rain also, rain runs behind that rubber lip on crowl that presses up against windshield, and also the drivers side wiper post runs down it and dumps water on engine both sides and the drain holes that suppose to drain water off the area where all your spark plug wells are is to high up, so water seeps in a lower edge of spark plug rubber boot, it will damage your coils, zapped 2 of mine...
