Get some Deoxit. Do ALL connectors. Clean ISV. Might want to check all grounds. Also sounds like you might need a new O2 and/or CTS. Idle should be 900+/-100rpm. Let us know.

All right, I've had it with my 91 Jetta Gli. The idle bounces from 1140 to 1200 rpm about twice a second and sometimes slower. There is a real bad exhaust stink too, like it's running rich. I have poked around the engine bay and checked for a loose connection at the dpr and all the connectors around the fuel distributor. I replaced the Throttle Body switches a few years ago (Renard - are you reading?). I pulled up on the plenum from the fuel distributor to the throttle body to see if it would change. To no avail. I did not take it off to check for cracks underneath. Can you advise what you folks did to alleviate such a crazy idle. It is intermittent, but I'd say once it starts it will continue for the rest of the drive. Engine temperature does not matter. Lately, on a cold start, the idle with hunt up towards 2K but come down to 1200rpm to start to piss me off. Any help would be appreciated. All this happened as soon as I had some major engine work done: rebuilt head.
