I have a 05 Mazda 3 and it threw a cel for evap leak large . At the same time it also started to make a strange ticking noise through the lower rpms . It goes away at higher rpm but is very noticeable at low rpm and at Idle? I replaced the evap solenoid because I read that it might be the problem but the ticking persist . Any help will be much appreciated.
