Well there is a rev limiter built into the pcm on your car. It is much lower rpm's in park and neutral. When u hit the rev limit of a particular gear selection, the pcm starts cutting out the injectors(fuel). This is normal. As far as the jerky feeling, the only thing I know of is a service bulletin that may apply to your car. It involves a revised torque converter for the transmission. It would only apply if your feeling this at speeds of approx 35 mph or higher when the torque converter lockup engages after a shift. Ask your dealer about a possible tsb for this if you think this may sound like your problem or search for tsb's(technical service bulletin's) yourself on the internet.

the idle speed control can be adjusted on the pump by turning the adjusting screw that stops the accelerator lever.

I just came up with that exact issue in my 2003 with 98K police crown vic. And the last time I had this issue in a 2001 police Crown vic it was the crank shaft position sensor. A $20 part and about 30 mins to put it in. located near the bottom of the engine. I had to un bolt the A/C compressor and push it out of the way a few inches to get to the sensor. If you have about 100K mile on it and its an idled heavy police car, this sensor should be changed out anyway. It can leave you on the road dead and some dealers have a hard time find out whats wrong as the OBD 2 does not see it as a problem when it goes bad or becomes touchy as I think mine is.

To update my earlier repair on the 2001 6 cyl Escape: When cold, and when the ignition was turned over but no accelerator pressure given, the rough idle finally returned the P0303 code again when the check engine light came on indicating that it wasn't caused by the plugs or the coil. FYI, I had replaced the intake manifold gaskets during the original repair and just prior to that I had replaced the fuel filter which was very dirty (I cut it open to see).
The repair manual referred to fuel injectors as a possible problem. I have run three tanks of fuel using different injector cleaning products and am very pleased with the results. Cold starts are much smoother and I am unable to coax out the P0303 code or any other code.
My opinion, change the fuel filter, use a fuel injector cleaner for a couple of tanks, change the plugs if the problem still exists. The coils were not the problem on my vehicle.
