2008 3.5 startup issue
My girl has a 2008 3.5 g6. She was complaining about issues she was having when trying to start the car. She told me that usually when she would be having these problems, and gave the car some gas on startup, it would start. I read on here that that was a sign of the throttle body needing to be cleaned. I took it off and cleaned it as best i could with throttle body cleaner. Not everything came off, some of the wear was really ground in and wouldn't come off. This was about 2 weeks ago. She text me today and said that it wouldn't start, and she was stuck with her brothers car. I really want to fix this problem she is having. She replaced the battery about a month ago i believe. Should i look into buying a new replacement oem throttle body, or what else can i do to fix it? What does it sound like is the problem? Any and all info and tips is greatly appreciated because i know nothing about these cars, and really want to fix this as she is really upset. Thanks in advance.
