I've changed the plugs..guess the one new plug I bought was foul and causing issues. The car is boosting as high as 15 lbs...could be the cold weather. I don't know what other gas to use. I only go to shell or sunoco and ONLY use 93. SLOW35I where do I get this fuel system concentrate? and do you work at a dealership or something that you are saying WE are starting to recommend it? Thanks guys!
