Fuji Fellow Posted May 10, 2006 Share Posted May 10, 2006 1988 Subaru, 1800 with throttle body injection. I read here earlier about a guy who was having idle problems, and traced it down to the big black rubber air-horn part that sits on top of the Throttle body. He was having air leaks in that part, upsetting the vacuum balance and messing up the idle. I think mine's doing the same thing. So what is the official name for this part? Or better yet, the Part Number? Or even better than that, where I might find one? Thanks, James Quote Link to comment Share on other sites More sharing options...
Mark Humble Posted May 10, 2006 Share Posted May 10, 2006 Intake air duct. Check at the wrecking yard, should be able to find one there. Quote Link to comment Share on other sites More sharing options...
ShawnW Posted May 10, 2006 Share Posted May 10, 2006 Id try silicone on it first to be sure thats what is causing the problem. If it is then replace the part. Quote Link to comment Share on other sites More sharing options...
