Hello all. I have an 88 turbo II and Im new to this board but was wondering if anyone out there would know of any VAC leaks that have a direct impact on boost. My car isnt building any boost, it idle surges about 6-700 rpms and seems to be leaking oil from somewhere underneath. There is a vac hose coming from a seloniod labled PRESSURE going onto the side of the intake manifold. This has a tear in it, but I dont think this is the MAIN problem. The throttle position sensor was changed about a month ago. The car runs like a dog, PLEASE HELP! email me at jamison182@hotmail.com or reply thanks very very much!.
