Bouncy bouncy idle?

This kinda goes along with my other post on the bucking at 60.

At idle, I'm swigning between about 800 and 1200 RPM's.

Thinking this may be a fuel pump.

Thanks!

Sounds more like a vacuum leak to me. Check all the vacuum lines, including the ones under the dash for the heater controls. Spray around the vacuum lines and intake, etc. with carburetor cleaner while the engine is running. If it idles up by about 100 - 200 rpm, you have a leak in that spot.

Thanks for the tip. 150K miles, there's bound to be a vacum leak. I'll dig around tonite.

Thanks!
