2001-2005 Escape ISSUE:
Some 2001-2005 Escape vehicles equipped with a 3.0L engine may exhibit idle speeds outside the specified range. Some 2001-2003 Escape vehicles equipped with a 3.0L engine and CD4E automatic transaxle may exhibit a transmission shudder. ACTION:
Follow the Service Procedure steps to correct the condition. SERVICE PROCEDURE
If the concern is a 2001-2005 Escape with idle speeds outside the specified range:
Install a new idle air control (IAC) valve with jumper harness included in the kit. The new Denso brand IAC will be installed with the electrical connector facing the opposite direction of the original (Hitachi) valve which is why the jumper harness is required. The original (Hitachi) IAC connector faces the front of the vehicle while the new Denso IAC connector faces toward the rear of the vehicle.
Referring to the calibration charts (Figures 1 and 2), select the applicable file and reprogram the powertrain control module (PCM) using the TSB Service Procedure and WDS/IDS release B40.5 and higher. Calibration files may also be obtained at www.motorcraft.com.
If the concern is a 2001 - 2003 Escape with transaxle shudder, drain, flush and refill the transmission fluid with MERCON® Multi-Purpose Automatic Transmission Fluid. Then, referring to the calibration charts (Figures 1 and 2), select the applicable file and reprogram the PCM using the TSB Service Procedure and WDS/IDS release B40.5 and higher. Calibration files may also be obtained at www.motorcraft.com.
When reprogramming the PCM use blank path programming. Select the proper file from the chart and manually enter the PCM part number or tear tag number to obtain the updated calibration file.
To Perform Blank Path Programming:
Connect WDS/IDS to vehicle.
Select "16 pin", select "All others, except those below", press TICK.
Screen shows installation of cable, press TICK.
Screen shows to turn ignition ON. DO NOT TURN IGNITION ON. Press TICK.
Screen shows progress bar, then screen tells you "No communication can be established with the PCM" and asks you if you want to retry? Select "NO". With the ignition key still OFF, press TICK.
Screen shows to turn ignition ON. Keep ignition in the "OFF" position, press TICK and you will be asked to cycle the key "ON" and "OFF" a few times. Please keep the key position in the "OFF" position through the key cycles.
Screen will show "The diagnostic tester is unable to communicate with this vehicle." You will be prompted to "select a vehicle from the vehicle list", press TICK.
A list of vehicles will be displayed, select ALL OTHERS, and press TICK.
Screen shows "To enable WDS to reprogram the PCM with the correct calibration", enter one of the following: Vehicle Calibration number (7 digits), Tear Tag number (4 digits), or PCM part number, press TICK.
Highlight the box next to the selection chosen, and enter ONLY ONE of the selections listed above. Press TICK.
Follow and answer correctly all remaining screens. Once PCM is reprogrammed communication should be reestablished and PATS system can be reset (if necessary) per Workshop Manual, Section 419-01.

Had this code for over 2 years on my 02 escape. FINALLY, found the solution. DONT replace your egr vacuum solenoid (unless you see broken pins on the connector). You can always test the solenoid to see if it still works if you suspect the solenoid is the culprit. Rather, most likely the problem will be in your electrical harness that connects from the solenoid to the pcm. I had no visible broken wires. However, in my case, my female connector harness that plugs into the solenoid was faulty. Replaced it by soldering the wires from a "new" harness that i got from the junk yard. If this fails for you, the problem will be almost guaranteed to be in either your pcm hardware or a broken pin at the pcm connection.
P0300 is a random misfire and P0316 is misfire at start-up.
If you have the V6, I would start by replacing the plugs and all the coils.
This is a little ******* the V6, since you have to remove the intake manifold, and the coils can be expensive. Coils are available on Ebay.
I've replaced all the coils on my 2002 Escape V6 after 100,000 miles. Typical V6 problem.
Sounds like you have a vacuum leak, a problem with the wiring, or a bad PCM. Check wiring for pinched, chafed, pierced, or broken wires. Make sure vacuum supply is good, and not collapsing when the vehicle is running. Beyond that, a trip to the dealer may be in order.
