I got a P0304 Code. (Misfire #4) Plugs installed about 150miles. I pulled #1 and #4 spark plug. #4 was white like it was brand new and not used. #1 was black oily gassy kinda. Would the injector be the last thing to look at?

Thanks.

Apparently it's relatively common for the intake manifold gasket to leak on the #4 cylinder -- try shooting some throttle body cleaner in the area and see if the idle speed changes -- is it running rough?
