Check engine light has shown 4 cylinders (all) misfiring.. and O2 sensor shows in code as well....

I have replaces clutch recently, and replaced plugs and wires... still mis-firing.. engining constantly bucking.. really effected by cold weather...

what may be wrong.. what course do I take next...?

my mechanics are throwing their hands in the air.
