Answer 1
i would check the evap system, vent solenoid and hoses you have a good chance leaking somewhere there -

Thanks for your answer however I still need some more help; where is this evap system and solenoid hoses? Are these the vacuum hoses? Thanks again. -
Answer 2
The EVAP system is spread from the gas tank to the engine. The code you had was probably for a 'large leak detected' and ONE of the possibilities is the gas cap , but that is as you've found not the only poss. cause. Less aggravation maybe , to have a qualified shop diagnose it. EVAP system leaks can be pesky. -
