Hello and thank you for using JustAnswer. My name is XXXXX XXXXX I will do my best to help you with your Chevy problem.

The code 304 is for a misfire on cylinder #4. This is the middle cylinder on the passenger side. Make sure you are getting good spark to that cylinder (remove plug wire with engine running). If you have a compression gauge you can also test compression to that cylinder. If you have good spark and compression then the problem is going to be a bad fuel injector for cylinder #4.

Where is the injectors located exactly please
Expert:  Dave Nova replied 6 years ago.
On your engine, the injectors are located inside the manifold. Remove the plastic upper portion of the intake manifold for access to the injectors.
