hippy, I have a fast idle and sometimes and fast-slow-fast idle. I'm guessing it's a vacuum leak or bad PCV valve since I've just had the thing in bits, and it wasn't there before I took it apart. The rubber 90deg connector from the hard vacuum hose to the PCV valve broke, and I dunno what parts to use to repair it. I also have another hard hose (rear valve cover to air cleaner) that is questionable. The rubber grips are deteriorated, so it wasn't a good fit. I used gasket sealer to try to plug any gaps. I've no confidence that what I've done will work, and don't even know if it's a PCV problem, though it did seem kinda grungy and a bit sticky. If I don't have any joy this weekend I'm going to have to sell my body on the street to pay a mechanic to fix it.
