MIL engine icon showed up after I changed an oil change. I filled the gas tank and tightened the gas cap and engine light still showed. I ran a diagnostic test and got the codes p0449/p0455 shows up as EVAP issues. 1 for circuit intermittent and the other for (gorss leak/no flow). My question is what exactly is wrong I want to see if there are any leaks in the wirings and solenoids/purge valves without having to change those good parts. I did some research found out I needed a smoke check-called local dealers which told me it'll run about $120.00-$200.00 is there anything else that you think might be an issue besides tightening and buying.
