Car runs great cold. When it warms up it will stall and miss fire. Will restart then dies. I had to restart the car 6 times the other day to get out of a parking deck. Maa air flow was replaced. No codes. Wife will not drive this car anymore.

my silhouette has an intermittent problem of loosing power mainly on highway. We can pull over shut engine off wait a few minutes and continue on for about 5-10 miles then it happens again. Engine light will come on the start to blink when loosing power. We have had a complete tune-up, gas filter changed, oil changed and now waiting for a Mass Air Flow sensor change. Hopefully, this will end the trouble. Up until 2 months ago car was running perfect until we got the fuel line cleaned at a Valvoline oil change store. I think I will never do that again!

Did end up changing C Position Sensor. Got CEL with this code after flooring the car up a hill to try to get past the chug/hesitation/lag problem that has many causes when accelerating under load. I still have that problem to a lesser degree but no more CELs that point to the position sensor.
