Good morning, my name is \*\*\*\*\* \*\*\*\*\* ill be helping you, so sorry to hear about the issues here on the Chevy. I know how frustrating it can be to deal with misfires. Now just so im clear are we only dealing with a P0303 code or also a P0300?

P0303 indicates a misfire on cylinder 3, if the [ignition coil](/topics-ignition-coil-chevy/) and spark plug were ruled out we would next need to suspect a fuel or compression related issue. i would start with swapping the injector for cylinder with a different cylinder to see if the code changes, as well as checking for power and ground to both the injector and the ignition coil to rule out an electrical issue. finally i would also recommend you test compression on all of the cylinders to see if theres a mechanical issue which is possible here.
Still not sure what you need?
Have a certified mobile mechanic diagnose what's wrong with your car, at your home or office.
