Hey! as title says, I just replaces spark plugs, thermostat, and a bad coil recently, only an occasional cylinder 2 misfire for codes. I did overfill the engine oil by a considerable margin on accident (dont do oil changes at night without your glasses kids) and drove it ~4-5 miles before overheating due to thermostat failure recently. During which I smelled a bad converter but don't smell at all anymore, converter doesn't rattle or heat unevenly. Car still occasionally drives completely fine, especially on a cold start and after driving for a long period. I'm thinking fuel injector in cyl 2 might be going out or intake issues?
