Try getting gas
tighten the cap till it clicks
Take it to auto zone, have him clear the error codes
And see if it comes back.
A common code for all cars is vacume loss in the fuel system, or loose gas cap.
Try it.

    then remove the cap

    clean it with a rag, put it back on.

    Have them clear the error code.

    See if it returns.

This car has 51,000 miles. Engine reads 16v ztec. Stumbled on acceleration. Cleaned the throttle body and mass air flow. Took it for a run and it threw the first check engine light, Had auto zone pull the...

All I am getting from your discription, is that you
have a code & a misfire ,you have yet to diagnose.

Except for replacing the wires, that should last the life
of the car,your doing okey

You now are embarking on throwing parts at it,
not diagnosing.

I can't tell you how to continue,as I don't know
if have any test equip or skills required.

You may have a bad ignition module or other

Again,test,don't install 1 part,unless something
tests bad.

02 grand marquis service engine lamp on, and idles a little rough

Your best bet would be to take it to Auto-Zone and have them read the code/s for you. It is a free service and can help lead you in the right direction. You can look at your gas cap, it can cause a rough idle and turn cause an engine code. Let me know how you make out.

95 Grand Marquis loses power between 45mph - 60mph

Mine was doing the same thing. I took it to one place and they charged me $107.00 for a fuel injection cleaning. That didn't do a thing. I then took it to a backyard mechanic and it turned out to be a bad spark plug. It has been running great ever since. Good luck.
