Hello, I have a Saturn aura xr 2007 3.6L, v6 and on Feb 28 2015 when headed to work 6am my car acted as it didn't want to start now I don't now if its because of the cold weather but it started it let it sit and run for 5-10 min and left. It drove fine no noises but only when I come to a complete stop is when it begun to rock/shake and make a little noise. Thinking it was from the cold I didn't worry but when I left work that even the temperature was warmer but it was doing the same thing as in the morning start and all so I decided to take it to a shop where they had run diagnostics they said I had several codes pending but the only one that wasn't was the camshaft timing and that all they said and did. And that all they said and did. Months before I went to a few places and they all said what they notice to be done is. Intake, crankshaft oil seal, cooling flush and camshaft position sensor so far I haven't been able to get any of that done also one place I trusted said to me there is no major leak and the sensor good just be bad but its not major to take care of at the moment. Now a little more history a few months before then I begun to put unleaded plus in my care rather then unleaded to save what is recommend is unleaded with a octane of 87 or higher I'm not sure what the octane has been those time when I put unleaded plus but as looking up things online there was a forum about "spark knock" I don't know too much about cars and what issues are greater then others so I have to trust that where I take my car they are knowledgeable and experienced. Help please thank you.

From using the wrong octane fuel you can get pinging you should always use the recommended fuel. Also if you could please tell me the exact code numbers not code descriptions? I know there was a bulletin about a cam sensor code on those.

My owners manual say a octane of 87 or more wouldn't unleaded plus be greater? I thought it was better for the car? The codes that they gave me are p0016/p0017/p0018/p0019/p0496/p011
