I got my saturn in August 2012, I have had no problems until I recently ran the gas down until the light came on, refilled the tank with 89 octane, noticed a miss during driving, then noticed when starting, black smoke and carbon deposits from the tailpipe. Have changed the plugs, and air filter(as it was dirty), and put gas treatment in the tank. Still has the miss during idle and driving, though slight but noticable and still has black carbon deposits coming out of the tailpipe. Im at a loss, and although im a female, im not adverse to getting my hands dirty on my own vehicle so ill do anything that "I" can, to avoid having to pay a big mechanics bill. Any and all help is greatly appreciated.
