04 Bonneville. Check Engine Light has been on for 6 months or so now. Is there any way to troubleshoot other than taking it to a dealership? I live in VA and understand it can fail inspection if not fixed. I do not totally trust the light because the instrument cluster seems to be a minor issue, mostly the gas gauge not working properly. I have also had a starting issue both when hot and cold out where I have had to give it a little accelerator to get her running. Other than that, true love!!!

You can go to autozone or advance auto parts to get the codes read for free. Get those codes and we'll be in business.

Fixing the gas gauge is a fairly easy, yet involved procedure.

There is a decent guide on how to fix it for about $25, and the broken gas gauge can trip a CEL.
