My wife has a 2010 Escape 2.5l 70k miles has anyone had issues with the throttle body ? It will run great till the light (wrench) comes on then it looses all power and after you stop, put it in park the rpm's wil surge between 600-1300. Shut it off wait 30secs. start it and its fine for a week or two then does it again. Can't get the code cause the dealer says the light has to be on. I wiped the throttle body out nice and clean now it was nasty. Hope this does the trick but I think I'll be changing it out.
Any info that y'all can give would be much appreciated.

I had a similar problem with two of my fords in the past five years. Have you had anyone check the power control unit for the engine itself? Sometimes the brains of the computer for the engine gets some glitch and had to be cleared and reset before the problem went away. The PCU or ECU or whatever they called it was sending wrong information to the engine, killing the power. Car would almost die on me, but engine kept running but would not get any response from the throttles. The vehicle in question was a 2007 and a 2009 Ford Focus with the L4 engine. Maybe something similar to that is happening here. Each time the car did this, the little wrench looking light would come on. Each time I took it to the dealer for checking out, the light would not come on and they said they could not do anything about it. It was very frustrating. Only after forcing them to reset the PCU did the problem finally go away for good.
I have a friend with a 2010 Escape with the v6 Flexfuel.
She is having the same lack of response from throttle body. It is an intermittent problem, but leaves here stranded more and more lately.
She took it in to the dealer to have it diagnosed and received this:
PERFORMED INSPECTION & DIAGNOSTICS
VEHICLE NEEDS THROTTLEBODY REPLACED,MASS AIRFLOW
SENSOR CLEANED & POWERTRAIN CONTROL MODULE RECALIBRATED
I was thinking that replacing the throttle body would fix the issue. I am just curious what is meant by re-calibrating the powertrain CM. Is this something that the computer usually adjusts on the fly or after a comp reset?
I would like to help her out but I don't want to swap it out just the have it still not work without re-calibration.
I just wanted to check. I know most shops pad the bill with fluff and recommended but not required services. Now I just have to find her a throttle body. I would worry about a junk yard part having the same issue. The local dealers say they are one back order until end of October. I will have to message one of the parts guys one here and see what they can find for me.
The throttle bodies have been on back order because they have been redesigned, and production has not caught up with demand. Our dealership gets them in sporadic shipments every week or two.
Replacing the throttle body requires that the keep alive memory be reset in the PCM, which can only be done with a scan tool on the 2008 and later Escapes. If you don't do this it is possible for problems such as erratic idle and stalling to occur. You may get lucky and the new throttle body will be "close enough" manufacturing-wise to the old part to work without problems.
Like most computer system manufacturers, Ford releases periodic software updates for many of the modules in the various vehicles it produces. In your case, reprogramming the PCM with updated software also erases the keep-alive memory. So, it would make sense for you to install the new throttle body, then take the vehicle to the dealer to have the software updated to get everything off on the right foot. The labor to reprogram the PCM should be an hour or less.
UPDATE:I installed the new throttle body and kept the memory. I figured if it didn't work I could clear it out and try that. I also let her know that she might still have to get the PCM updated by the dealer if problems still persisted.
After the install there was an immediate difference in smoothness of idle, power, and smoothness under load. She has been driving it for a couple weeks now, and has been doing great. I still recommended that she have the update done at the dealer. She has not done so since the truck has been doing so well.
We have been informed that Ford has issued an extended warranty for defective throttle body assemblies and sensors for 10 years or 150,000 miles from the data of original purchase. For vehicles past this time limit, the warranty is reported to be valid until January 31, 2015.
Affected owners should contact Ford and mention Consumer Satisfaction Program 13N03.
