like all of you guys my revers also crunched every time,

regardless - i had a problem with my idle rev's, after some work on the throttle and idle valve my idle went from 1200 to around 750-800...
and magically the crunches disappeared.

alto my rev's are now back to 1200 due to some vacuum issues and the crunches are back...

can i get a second opinion on this...
