P0304 : cylinder number 4 misfire.
It is probably the coil on cylinder number 4. The easiest way to troubleshoot it is to swap the coils between 3 and 4 and see if the misfire then shows up on three.

That error code is for a single cylinder misfire. Bad spark plugs or wires can cause this as well as a bad fuel injector.
Stop by http://www.coloradofans.com there are different people that have had that problem. you can probably message them personally and see how they got to that problem.

Cylinder #4 is misfiring in an engine with 4 or more cylinders. Engines have a firing order that is used to number the cylinders and it depends upon the engine which one is #4.
Cylinder #4 misfire
A misfire caused by the ignition system exhausts unburned fuel into the exhaust system that enters the catalytic converter and causes its temperature to rise dramatically. An exhaust issue could cause for cylinder 4 to misfire. The camshaft lobes, which are responsible for opening and closing the intake and exhaust vales, are another source for a misfire and rough running engine. The cam lobes for the No. 4 cylinder should be inspected to see if they have been worn down due to lack of oil or other mechanical problem. A damaged camshaft lobe will not allow a valve to open properly if at all.
Was an intake manifold gasket for me.
