vacuum leak
Hello everyone,
I just bought a used 02 saturn ls. The idle runs around 2500 rpm and I thought it was the IAC valve. Replaced the valve and it still idles high. My next move is to check for vacuum leak. I dont know where to start. I was hoping someone to tell me where to get a diagram of the vacuum hoses, or any other place where there is a potential for a vacuum leak.. Please help.
Thanks

There should be a hose routing sticker under the hood. If not there, then I don't know where to tell you to get one. As far as finding a vacuum leak, just get some WD-40, carb cleaner, brake cleaner, etc and spray around your intake and throttle body. If the engine speed picks up, there's your leak.
