HI,
I am sorry that you have not been helped yet.
Check emission light can be set due to gas cap not sealing, vacuum leak in one of around 15 vacuum hoses, faulty leak detection pump, faulty evaporative emission solenoid valve, fuel in the vapor canister, leaking fuel filler pipe, or about 15 other causes.
The fault codes need to read in the onboard computer, which will give the area of concern.
DRL warning light is on due to either faulty DRL switch, DRL control module, short or open in the wiring harness
