EPC was on due to a twisted vacuum line that controls the intake manifold flaps. Lines untwisted intant power. On a side I am putting my winter tires on tomorrow just wondering if it might be too soon as it is about 55 degrees daytime 45 at night here in NY. Try to post pics later on

I live in metro Philly and usually change mine Thanksgiving week, and have for years with all my cars. I run summer, not all seasons, for my summer tires and dedicated snows (Dunlop 3D) in the winter. 19in. Second set of factory Titanium rims.
