Hello I just had my oil changed and thought my car was running fine until yesterday I put gas in my car and now its idealing high when its sitting still. I starting noticing it when I was sitting at a light and my engine is roaring and I'm not moving. I don't know if I need to have my fuel filter changed or what.

Has the check engine light come on? I don't think the fuel filter would cause this type of problem. It sounds like a sensor problem. However, I need to know if the check engine light is on to determine the code.
