Need help with vacuum lines
Okay, so I'm pretty sure I have a vacuum leak somewhere but I can't find it and brake cleaner isn't working. I'm getting a p0140 secondary air injection malfunction. I've already checked it and it's lines and everything is working fine. Can someone please help by telling me where the rest of the vacuum lines are located so that I can check them each one by one? I can hear a faint hissing sound like air leaking, but I can't find specifically where it's coming from. But it sounds like somewhere on the drivers side. Thank you for your assistance!
