Hello everybody i have a 2012 lancer and im having trouble getting her to idle right, I replaced the plugs and I replaced 2 coil but she still wont idle right. I also noticed that I can air a air suction sound around the throttle body. I replaced the throttle body gasket and im still getting that noise. I feel like I replaced a gasket that didn't need to be replaced. I need help this is my daily vehicle and I can't keep driving her like that.
