well i jumped the ecu this morning and i got these three codes. Cylinder misfires. What do i do? i talked to my mechanic buddy and he said worst case scenario is i broke a piston ring o somemething. What else can cause misfires? any help is greatly appreciated. The car is a b16a2 turbo in it. The check engine light started flashig one day while i was in boost.

 

check the ignition system: plugs/wires/distributor(cap and rotor), I did a minor tune up and it got rid of misfires.
