The car is never fine-- it just doesn't turn off all the time. It is intermittent, which makes it one hard problem to fix, apparently. To my knowledge they just checked this system in the car, and tested to make sure that the car was not getting a lack of fuel. It has had the test run a few times to make sure it gets the fuel it needs, and aces it every time. We're starting to think it is an idle problem. We can watch the normal idle speed drop more and more as the car is in hotter weather w/ the ac on...

One more idea: although it should throw a code, have them take apart the EGR and intake flap valve. It looks like a throttle. There have been a few cases where the gears that move the valve get stripped. Maybe by some chance the valve is closing, causing engine starvation. Aside from intake clogging, perhapes the EGR valve is somehow malfunctioning causing the engine mangement to get confused and cut fueling.
