low RPM at stop

when my cavi is stopped the RPM's go up and down slightly, not below .5 but not above 1 - it sounds almost as if it will stall or die out - any ideas?

That is what the idling RPM should be. Or does it make odd sounds?

vacume hose or line what ever U want to call it

the car just shakes sometimes almost like it wants to stall out and the RPMS go crazy up and down...... what is the vacuum hose?

yes sounds like a vacume hose - it is rubber hose that runs vacume pressure - in your case sounds like it could be a vacume leak - maybe a cracked hose or just fell off - just some suggestions - check the lines goin to the TB - you can pick a vacume tester pump at the parts stor for like 30 - 40 bucks - there is instructions on the package on how to use it or if its a Advanced Auto the clerk will show u how to use it in the parking lot
