The insulation on a spark plug wire or wires could possibly be breaking down. An easy check for this is to start your vehicle at night (make sure you do this in a dark area with no street lights). Open the hood, have someone rev the eng. to around 2500 rpms and check all the wires to see if any of them have spots that are glowing. If there is one doing this, replace it and problem solved. This is just an idea and hopefully I'll be something that simple.

Catalytic converter stopped up. Pipes got red hot. Replaced Cat. Conv. car runs good, then started random misfires, pipes got red hot again. What is exhaust part that is downstream of Cat. Conv. could it...

If the exhaust system was plugged the engine wont run, normally. It will start and idle until the back pressure is such that it can't take in more air/fuel mixture and then stall.

After the converter, there may be a resonator, and then the muffler. Is any exhaust flowing out of the tail pipe? You might try hooking up a scanner and see what your oxygen sensor(s) is/are doing.
Also, scan the MAF(mass air flow) sensor assembly.
Sound like the engine can't breathe, and its getting to much fuel.

Catalytic replacement

A bad cat will sound like it has marbles inside when you hit it with a rubber mallet. A good one will be solid metal with no loose platinum coated honeycomb core. I'd suggest if you go with aftermarket replacement choose a higher flow converter which will increase HP and better fuel mileage. Depending on your engine model, you'll need two parts to make it work, they are sold separately and need both. You can find it here Techtonics Tuning

The IAC valve requires resetting .
First locate the IAC valve located on the side of the throttle body and has 4 wires going to it .Procedure is as follows
Ignition key on ,unplug the IAC ,turn key off ,reconnect the IAC .do this 3-4 times .restart the car and hold the rpm at 2000 rpm and slowly lower until it idles by it self .

2000 ford explorer 4.0 x-engine is stalling, missing and lose power while driving

I personally would check the fuel pressure. Then I would go back to the coil. I have seen brand new bad coils out of the box. The symptoms of a loss of power point to this component, especially if the car idles well, but loses power when accelerating. Please do not rate this reply - we all are left to grasp at straws since you have changed pretty much everything. Good Luck. Please post the final fix of the problem.
