My 2006 G6 GT has 135000 miles on it and lately I've been having some problems... I'm hoping someone can help me out. First off, lately, I have to give it gas to start. Then my check engine light has been coming on an awful lot. Not every time I start the car but often enough. Besides the check engine light, now its started to say "engine power reduced"... Not sure whats going on, any suggestions on what I should do? I did take it to my local mechanic and he said that he performed a scan however the day I took it to him the check engine light was not on, he said to bring it back when the check engine light is on again and he will scan it again. Does he know what he is doing?
