OK guys here's another.

How do I go about detecting for a vacuum leak, with out taking it in to the shop to get it hooked up on propane. Are there any home procedures? Does anyone know a good site?

Thanks in advance

A mechanic's stethescope and a good ear always seemed to work for me.

Get a carb cleaner/ throttle body cleaner. Start spraying the vacuum lines. If the engine speed increases (RPMs go up) you have found the leak.

Good Luck.
