LINCOLN LS ENGINE PROBLEM

2004 Lincoln LS

Engine Performance problem
2004 Lincoln LS 6 cyl Two Wheel Drive Automatic 40,008 miles

Good morning. Check engine light is on but not blinking. Engine has low rpm (2500 at idle with pedal fully down) Misfire occurs. My mechanic dried water from coils and plugs, it did not appear to be oil or coolant. He thought I had the engine steam cleaned. After his service the car drove normally until 78 miles then problem reoccured. I did not drive in rain or snow but the moisture reappears around the coil and plugs with check engine light on. The misfire may have killed the catalytic convertor but thats another chapter.
This is the third time he's dried the coils & plugs but he needs to firgure the source of the water and that's my question.
Also will new boots or gaskets in the wells solve the problem?
I'd be happy to give you a nice bonus if you come up with the correct solution. If you do, I think there will be a number of other probelms you can help me with.

What are the code numbers currently in it?

Hello,
The code numbers indicate a bad catalytic convertor nothing more. In fact I was told to have it replaced, but the misfire is probably what killed it. So I want to get the moisture problem fixed first.
Thanks

PO420?

The converter may be causing the misfire. I understnad what your are saying about the moisture, but it may not be the cause of the drivibility
IF there was a misfire from the ignition, misfire codes would be present, PO300-PO308, If you don't have those, I'd suggest to start focusing on the converter.

The converter can break up internally, your is under factory warranty. There are good for 8 years/80,000 by federal law.
