Smog Test FAILED; Gross Polluter!

Thank you for your response. 1.) The fuel cap has been replaced. 2.) The oil change will be performed. 3.) I will have the EVAP canister and throttle body cleaned. Thank you again, hopefully this will work and I will update so as to help out the next Joe. Update (05/12/2015); 1.) The fuel cap has been replaced. 2.) The oil change has been performed. 3.) The throttle body has been cleaned. 4.) All Vacuum lines have been replaced. The EVAP canister; I have been unsuccessful in finding a new one, apparently this part is no longer being manufactured. Although The vehicle PASSED all the ECS, it still tested as a GROSS POLLUTER, the HC (PPM) & the CO (%) are still showing high measurements. Any ides as to why and what it could be?

Thank you for your well wishes.
