I got belt from my FLAPS, finally figured out how to move the alternator to tighten the belt. however, the blet still flaps a lot and eventually will fall off. the belt appears to be chewed up, i dunno why. i dont see a way of checking if the fan and alternator pulleys are aligned correctly w/o pulling the motor.

also, with or without the belt on, my car idles really weirdly. it revs and revs from flat line (almost stalling) to about 1300 rpm. just this constant up, down, up, down...etc between flatline and 1300. there is a distinct continus HISS (is this normal for 914's?) if i cover the inlet for the airbox.. the car idles at about 1100rmp, HISS still present, but no "up-down-up-down..." revving. what am i misssing here.

btw, no mods to air intake, stock airbox with regular airfilter element.

it is NOT normal. you have a vacuum leak, and it is very likely primarily responsible for your wonky idle issues. you'll need to remind us what kind of engine and FI you have, and someone versed with /4 operation can guide you from there.

meanwhile - what you can do - find that vacuum leak ! sometimes it helps to use a 2-3' section of 3/8" (or so ...) plastic hose. stick one end in your ear, move the other end around in the engine room like a stethoscope and zero in on the source of the sound ...
