I just recently purchased a 2001 Ford Escape 3.0 V6 for my 16 year old son. The car was well maintained and basically highway driven by its previous owner. The car has 150k miles on it. After our original test drive of about 30 minutes the car began to run rough. Also, the check engine light is on. We took it to a local reliable auto repair shop and had them look at it. They ran a diagnostic and the codes pointed to the following: The #1 ignition coil could be defective or the secondary ignition plugs, wires, cap, rotor could be the cause, or poor electrical connection or circuit fault and finally, driver circuit fault/ignition module or PCM. Also he said possibly the throttle position sensor. Unfortunately you have to remove the upper intake manifold to gain access to the coils and plugs in the rear of the engine. We did so and replaced the #1 ignition coil, we replaced all 6 spark plugs with Motorcraft plugs and the throttle position sensor. Upon cold start the car ran great again for a small period of time. I feel like this problem must be heat related whether it be engine heat or outside temperature. Each time after letting the car cool down the car again runs well for a short period of time. It does feel like it is just a spark plug that is missing but obviously that is not the problem. After replacing everything we stated above, I had another diagnostic done at Auto Zone and the exact same code and probable causes came up. I feel like there must be some small sensor or electrical malfunction. We have had other suggestions that maybe it could be the fuel filter or massive airflow sensor (MAF) and possibly even the computer module (PCM).

Is there anyone out there that has possibly had this same problem with their Ford Escape? My son would really like to drive this car more than 30 minutes at a time without having any problems.
 
i would say the computer is bad. the computer is spitting out codes and you fixed what it said and now it is spitting out the same codes. only a computer malfunction can do this.think about it. the car ran fine and then acted up.you fixed it and it ran fine and acted up.try this first. remove the positive battery cable for five minutes and hook it back up. this should reset the computer. if it runs fine for half hour and acts up again its the computer
 
What are the codes? "HO2S indicates system lean" ??? Fords are prone to vacuum leaks. Hoses mainly. listen for a loud hissing sound coming from the engine. And btw, this car does not have a distributor cap or rotor button, it's a coil on plug ignition system.
