Things found wrong with my car today: "Fuel tank needs cleaning", "glow plug circuit low input in bank #1" and "input voltage in oxygen sensor 2 is too low" WEEEHOOOO I cant wait to get these fixed

 

You have a big problem, you don't have glow plugs in your car. Its a gasoline motor, only diesels have glow plugs, lol

 

that makes sense, the guy said he had never seen those before...

 

I can't see a gas tank ever needing to be cleaned. It kinda sounds like you're being taken for a ride here. Has your car actually given you any trouble to warrant taking it in to a a mechanic? I normally won't take my car to the mechanic unless I have an idea of what the problem is and it's something that I can't fix myself.
