Check for vacuum leak. Also if it has over 80,000 miles on the odometer replace the spark plugs and plug wires.
I just had my 04 Escape checked out at a mechanic and the computer said it was the egr valve. This started happening after I ran out of gas. The mechanic thinks that may have been part of the problem cause some junk may have made it past the fuel filter and gunked up the egr valve.
- I would first check for vacuum leaks, then I would test or replace the IAC (idle air control), then if all checks out, do a compression test. All cylinders will have to be within 10 per cent of each other to have a steady idle. Note that the upper plastic intake will have to be removed to test the back bank.
This guy is RIGHT it is a VACCUME LEAK! CHECK this out!
Im not a mechanic but I have had the same problems with my 2001 Ford Escape. I changed the Mass Air Flow Sensor (MAF sensor), Idle Air Control valve (IAC Valve), Positive Crankcase Ventalation Tube (PCV Tube) and nothing worked. You do need to check your PCV tube to see if it has collapsed if so change it $26 at Ford house. What finally fixed my car was when I changed out the upper and lower intake gaskets $9 at Auto Zone. 4 of my upper gaskets and 2 of my lower gaskets were leaking. If you do decide to change the gaskets out, replace your PCV valve $6 easy to get to once you remove the intake to get to the lower gaskets. Change your spark plugs out with factory Motorcraft plugs $4 a piece. I did all this and my Ford Escape runs like a charm. Hope this helps you out. If you do this yourself make sure ALL VACCUME HOSES are put back on.
Vacuum leaks can be hard to find, I use WD40 instead of a smoker, whenever idle changes when spraying around hoses/motor, I have found my leak. Works everytime!
Hey, before you tear everything apart, if you don't have any warning lights on, disconnect the battery and leave it disconnected for about 5 minutes. Then reconnect it. This resets the computer. Mine ran smooth as silk after that. (2001 V6 Escape).

A 2006 Ford Escape uses standard 5w-30 type motor oil. This provides a good balance of viscosity and protection for the engine.
An A/C compressor takes about 6 horsepower to turn it and when an engine is idleing, it is producing about 30 hp so when you take away 6 hp from 30, it puts quite a load on it. There is also a device which increases the idle speed when the A/C is switched on. If this is not working or the idle is set too low then rough idle may occur.
i have a 1988 Ford Bronco XLT 5.0 4x4. The truck will start and idle for about 15 to 30 seconds then acts like it has no fuel and dies.
Minimum of 10 psi at idle, 20-30 at idle is average.Minimum of 10 psi at idle, 20-30 at idle is average.

could be the egr valve is dirty and needs to be cleaned. if there is soot build up, the valve may not close all the way which can cause a rough idle. if it ever stumbles while accelerating, that can be from it not opening when it should. cleaning it can be an easy 30 min job that anyone with basic mechanical skills can do. sometimes.
Hey Bill== An a/c takes about 20 horseower to turn the compressor and a 4 cylinder is developing about 30 horsepower idleing so it will slow down and be rough. Sometimes there is a solonoid to help compensate for this but it doesn't help a lot. GoodluckJoe Check your idle air control valve for lack of movement. When you turn on your A/C it puts a load on your engine, the IAC valve compensates for this by increasing the idle. If it's bad or is not being controlled correctly that rough idle you described will occure due to the load on the engine. Regards, Kevin
autozone has them for under $15, and about 30 minutes of your time
Check your owner manual to be certain, however, I believe 30 psi "cold."
