OK heres the scoop got new low comp shortblock for supercharger fun in and service engine light came on. Code was misfire in #1 cleared it checked coil, plug was OK. Put on C&L plenum and 70 mm TB to get it ready for tune at kauffman monday... but check engine light started blinking and it says misfire in #5 now misfire in 1000 rpms, and it blinks and car hesitates when you just driving normal. Does this all have to due with the car needed the tune that badly or is it something more serious???
