well.....my idle is messed up. it idles like 1800-2000rpm and then it drops. one of my buddies told me that it could be a vaccum leak and to spray carb cleaner around the IM. and i did and nothing. i started spraying around the TB and i sprayed right at the TB Spring where the throttle cable hooks up at, and the idle drops. can anyone help me to fixing the problem? thanks
