    Can you move the metal elbows into the throttle body? They leak too.

      I'm not sure what you're talking about. Can you clarify?

        The rubber hoses from the ICV and the brake booster go to metal elbows that are pressed into the throttle body. They leak sometimes (mine did). If you can wiggle the elbow, then it DEFINITELY leaks.

          oh the right side of the throttle body you will see one or two metal elbows with the thick vacuum lines coming out and it goes into the brake booster. If those are excessively loose it will create a vacuum leak and cause the car to run rough. Personally I've never had this problem myself. they should be able to move a little but should be very snug.

            Just got the car running again still idles quite choppy. Could an exhaust leak near the muffler cause a bad idle? I wouldn't think so. I haven't been able to locate a vac leak, I've sprayed with carb cleaner a couple times, no change.

              Have you tested your icv? Is it making a buzzing sound? If not that could be part of the culprit. I have a used icv thats only a year old if interested. pm me and can send you pics and give you a price
