Have you listed to anything that I and others have said in your previous threads which ask the same question?
Check the vaccum hoses, as you most likely have an air leak!
Early cars had MAF'S, later cars had TMAP which you cannot see as they are inside the inlet manifold.

If not disconnect the battery AFTER you ensure you have the radio code etc for a few minutes and reconnect, this should sort it.
It may well be a faulty TPS.
So you checked the vaccum hoses?

I guess the EML has only illuminated since unplugging the TPS? I would have thought that once it was reconnected it would register as well and extinguish the light.

When you unplug TPS the ECU will use a typical static value for that input as part of LOS (Limited Operation Strategy) Ford speak for limp home mode, so you will have limited performance, all the time this is active.
As a tip spray WD40 sparingly around with the engine running, if the engine note changes, then this is a sign of a leak (Probably best to clean off the vaccum hoses after)
