Recently installed a procharger kit on my car by myself and right after I started it up the idle was going crazy but after a few seconds it settled down. Thought the problem could be fixed with a performance tune but it still idles crazy when its cold and when I drive it the engine sputters pretty bad when I'm just crusing in it. Check engine light went off ran the dtc scanner gave me code p0300 and code p9128.....anyone have any ideas on what's going on....
