Need Help - I live up in NB Canada - Gets cold up here, last year my wife's 06 G6 would start, but sputtered - with engine power reduced error. could not drive normal speeds. After taking it in 2-3 times they said it was the throttle body and 1 injector so they replaced those parts. Anyways today it did it again, It seems to only happens when its -30 to -40 out. Anyone know about this error , or had it fixed right? It has happened 4 times so far. 3 times last winter, and 1 this year. Today it fixed itself after running car for 5 min. I am at 70000 km, no warrenty anymore.
