i have a vaccuum leak, but i cant seem to find it. Does anyone know of a good method? I've heard of some people putting baby powder all over the engine to see where it "sprays"
does anyone know anything else that might work????
thanks

I've heard of people spraying carb cleaner in places with the engine running (if possible) and see when your idle raises (as the engine sucks up the carb cleaner). I've also heard of someone forcing air into their intake (with the engine off), and spraying a mixture of water and bubble bath stuff, and wait to see bubbles forming. I've also seen where someone put a small funnel-type fitting on the end of a piece of vacuum tubing, on the other end to their ear, to move it to different areas to hear a vacuum leak.

Or you could just go over every vacuum connection, make sure there are no cracks, and that all connections are secure (my method). Don't forget the main intake tube to the TB.
