2nd vehicle is down!!! Help!!!
I have a 1998 F-150 with a 4.6L that misses pretty bad at low rpm's. I can floor it and the stumble disappears. No code, no nothing? Where do I start?
I already have to put a fuel pump in my Expedition this weekend. Now this. Help!!!!!!

I did smell antifreeze when I was checking things out
My heat wasn't heating very well and I added more coolant. That fixed the problem.
About 2 days after I did that, the miss started. I'll check it out.

Antifreeze in the plug hole - leaking at the clamp
I checked the rear passenger plug and sure enough there was antifreeze all over it. My question now is, how do I get the plug out. I've tried and tried and cant get the spark plug socket to grip the plug (yes it's the right size - I checked it on the new plugs). The socket just turns and doesn't grab. Any ideas???

What does the exhaust look like when it comes out the tail pipe? is it like a nasty toxic waste dump, and really white? if so you have some type of a fuel leak, where extra fuel is getting in. This would likely give you SES light and a code. If this does not exist, i would severly look into the ignition system- spark plugs and wires, even the ignition coils. I know its not easy to remove them, but do your best, if you have to swap coils to see if the misfire changes. Check the plug condition, check for excessive fuel on the plug or corrosion. Might as well buy new plugs and put them in the ones you take out. A spark plug wire shoudl measure 30K-70K ohms end to end. and YES, spark plugs DO GO BAD! internally they can fail, and the power finds ground without traveling through the electrodes.
Are you having problems starting or is starting fine? If you have to put your foot to the floor to start, you have a fuel problem, pedal to the floor shuts off the injectors. (the tps sees greater than 90% and shuts off the injectors) Pedal half way pulses the injectors, meaning you werent getting enough fuel.

Did you get it back to normal again? Hopefully so. To answer your question, use compressed air to blow out the anti-freeze and any other debris that is down in there. If that doesn't allow the socket to grip the plug, then use a mirror to see what else is down in there that is in the way of the socket seating on the plug. Good luck!
