Pontiac Repair: 2002 pontiac grand am 2.2L (4 cylinder), piston rings, engine harness

Question
computer is spitting out P0300 code ( multiple misfires) found it to be misfiring two cylinders #2 and #3.  checked coil packs and replaced.  I am still having the same exact problem.  Any ideas?

Answer
Hi
MANY things can produce misfire code.
Coils, plugs, wires, ignition module, injectors, injector wiring, engine harness wiring, pcm, cam, crank, valves, piston, rings.
My BEST advice would be to take it to a good repair shop and have it properly diagnosed.
I hope this helps
good luck
