Pete,
To find the source of a vacuum leak perform the following. Start up
the engine and let it come up to normal operating tempeture. Grab a
can of WD-40 and spray it at different spots (one by one) that you
think there could be a vacuum leak. As you spray a spot, listen for
any change in the engine. Once you hit a spot that has a vacuum leak,
the WD-40 will get sucked into the engine and cause a distinct rev in
the engine. If unsure, spray it again while listening for the change.
This is the safest and fastest way to pinpoint the problem. Be sure
not to spray to much (so there's not a lot of cleaning to do
afterwards) and make sure you don't get any WD-40 on the exhaust,
it'll smoke and burn off.

Hope this helps,

Steve Rubano
