    if you have replaced all that already, than you may have a broken intake gasket. does it idle fine or do the rpms go up and down a bit while at idle??

Chrisker Pacificathe check engine light was on computer code 0304, we did a tune up, change and the check engine light shows again with the same code 0304

this is a misfire in cylinder #4 of the firing order. You either have a bad spark plug or a bad Coil on Plug (COP) assuming you have a COP system. Or a bad plug wire if you have a distributor. Outside chance no fuel is flowing through the injector due to wiring, bad injector, plugged injector.

Those codes are Misfire codes, I would change the spark plugs, check or replace coil packs or wires, check or clean fuel injectors, and replace fuel filter.

Steam coming from passenger side of engine on occasion, not constant. Light on so read code as 0304. Misfire on 4. Changed plugs got all clean but dirty 4. after change same problem. code reads 0304. need...

Sounds like a blown head gasket. Check for water in the oil. Check to see if water and/or steam coming out of exhaust pipe. If you are getting steam, you are losing water. Sooner or later it will overheat.
