I decided to clean my '98 Throttle body and idle control valve following Advise on Pedro's Garage and Pelican Parts because of a intermittent idle problem, when the LOW idle would sometime cause a stall. When I put things back together, the idle now has the opposite problem, hunting from 1100 to 2100rpm's. I replaced the ICV gasket, and the seal between the throttle body to the 'T" plenum. I'm 99.9% sure the rubber seals between the 'T" and the plenums are seated correctly...BUT I noticed two potential problems upon inspection and re-assembly. Number one is that both rubber connector seals has has a port that opens to the outside. the right side I believes goes to small black tube that goes to a check valve below the right intake plenum. The left side goes to ... no where... (creating a nice leak). Does anyone know where the left side port connects to ? Is that factory Porsche or do I have it installed wrong ? Second problem is that I noticed some fine cracks on the ICV itself. When I was cleaning it with carberator fluid, these would actual weep a bit. Does that mean I need to replace the ICV ?
