Hey guys so I just finished installing my Stillen supercharger kit. Install went smoothly so I loaded the tune up via UpRev that Stillen provided. Started the car and seemed to be running “ok” until I reved it a bit and noticed a misfire. CEL came on/ started blinking. I got code p0300, p0301 & u1204..ugh. I started my checking for spark in all cylinders which checked out and noticed cylinder 1 plug to have no soot/ fuel smell on it. All other cylinders were normal so I’m wondering what would be causing cylinder 1 to have no fuel? Before I pull the Stillen intake manifold (massive pita) to check cylinder 1 injector I’m looking to see if there could be something else. Maybe something related to the u1204 CEL?
