Jimmy Notchback Posted November 14, 2005 Report Share Posted November 14, 2005 My stepdad has an 82 corvette with crossfire injection. The car stays in high idle and won't drop down. He tried to adjust the idle and could only get it to low or to high. I know nothing about these cars so he asked me if I could post on here and get some ideas on how to adjust it properly or what the problem might be. Thanks in advance for any help.

Jimmy Notchback Posted November 14, 2005 Author Report Share Posted November 14, 2005 It's not my car and he collects vettes. So that means that he is not into making them faster. He just wants it to run right. Quote Link to comment Share on other sites More sharing options...
speedytang Posted November 15, 2005 Report Share Posted November 15, 2005 The throttle bodies get a vacuum leak in the throttle blade bushings. This is a very common problem for the Cross-Fire units. Go to a Corvette Forum and they usually have a section on problems and that is the most common vacuum leak for the 82 and 84 Corvette. The bushings if I remember are machined into the units and some companies offered a service to rebuild the units and machine a new shaft to stop the vacuum leak.

Dave1647545494 Posted November 15, 2005 Report Share Posted November 15, 2005 you can check for said vacum leak by lightly misting some solevent around the area you think the leak is in if the idle changes you do indeed have a leak good luck Quote Link to comment Share on other sites More sharing options...
