2004 AWD Outy with over 100,000 miles bought brand new in 2005.
Driving car normally and for no apparent reason car will not accelerate above 10mph. Get out of traffic, pull over shut down and restart and everything is normal.
This happened about 4 time in the last 2 years.
Everytime I bring it to my shop they see the P2138 code but are unable to find anything wrong after testing and clear the code.
Did some research and found TSB -06-03-011REV issued by Mitsubishi Autgust 2006 describing this as a computer error and needs to be reflashed.
I do not recall ever having this reflash done when it was under warranty and had regular dealer servicing.
Called my local dealer as I do not live close to the original dealer where purchased. They want to charge $60 to reflash but the tech said on the phone "doesn't sound like it's the computer, may be the throttle body". I have a deep distrust of most dealers from past experiences and know they will try to rake every $$$ they can out of customers with older cars so I need advice.

Anyone on this forum have this problem?
Was your computer reflashed?
Should I call Mitsubishi direct customer service and see what they say?

This is a serious issue and could cause accidents.

Have not had this happen on the Outlander, but had a similar issue with a Jeep Cherokee, drive at a steady pace, motor would cut back to idle and would have to shut down and restart.
Replaced the TPS, (throttle position sensor, same function as APPS), problem solved, never came back. AFAIK, it is just a rheostat that alters a voltage signal to the computer to adjust the injector pulse width. If the computer gets an out-of-range signal, it will default to a limp-in mode.
Hope this helps.
