Exclamation 00' RS-New motor CEL Code = Misfire

HELP, I just got a brand new ej25 bottom end installed, with exedy clutch + flywheel, Borla Headers , Apex-i exhaust, UR pulleys, and Magnacore plug wires. The CEL keeps coming on so I replaced the coil pack because #3 had some corrosion on it. Then 2 days later the CEL came on again, but it still reads that there is a misfire on all four cylinders. My car inspection is in 2 weeks.

jelton - Make sure you do the cam timing correctly. So it'd be best to check there first. Otherwise; you may want to put back your old crank pulley.

The light weight flywheel could also contribute to the misfires, causes imbalance in the crankshaft. OBDII misfire monitor uses crankshaft imbalance to determine misfires.
