I just had my number 4 cylinder's fuel injector replaced and within a day or so my check engine light came on, I read the code, and it is throwing P0304. Could it be something I can check myself and possibly fix like a lose wire or something of that nature before I have to take it back to the shop for repair?

Do you
have the same problem?

That codes is til a #4 misfire, check the plug wire oor spark plug and compression. Check fuelpressure as well. Any of that can cause your problem
