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!
