What is your question?
I can hear a hissing sound in the engine compartment that sounds like a vacuum leak resulting in rough idle. The engine smooths out at highway speeds (75 mph) How do I access vacuum hoses?

What is b-12? Where do I spray it? Thanks.
Berryman/B-12 carburetor choke and throttle body cleaner.spray it around your vacuum lines,when the idle of the engine changes,you found the hose leak.most autoparts stores carry it.
Thank you. I will go into town and get a can.
don't get crazy spraying this stuff on a hot motor - it'll catch fire. just spray little spurts near connections.
