A faulty ECU is one of the most common no start or random stalling & low power problems with these cars. These can also cause issues with erroneous check engine lights as well as emission control malfunctions & cold or hot start problems. If your car does not have these issues but you intend to keep it a while, I recommend our customers keep an extra ECU in the trunk. These units now have to be special ordered from most dealers new for big $$ (often times over $1000!), and you can never find the right one when you need one. Even now finding a good one second hand is getting to be quite difficult as these cars get older.
