Intermittent Dying?

So.. I went on a cruise with the Ohio Bimmers forum. It was pretty intense to say the least. My little E30 had some trouble keeping up with all the M3's, M5's, and the M1's, but I did very well on corners to keep up. After the first leg of the cruise, my car started acting up.

It runs fine while driving, but every now and again I'll pull up to a light or stop sign and my car will randomally die. Sometimes it'll back its idle down to 450-500 but not die, then the next light it'll just die. Within the past year I've replaced: fuel pumps, oxygen sensor, spark plugs, fuel filter, spark wires, engine coolant temp sensor, timing belt, distributor, rotor, valve cover gasket, almost all vacuum lines, and alternator. There's more but this is all I could remember from the fuel and emissions system. It never did this before, but now it does. Anybody know where to start on this?

Idle control valve. Test it. You either have a vacuum leak or that valve is not working. A vacuum gauge would tell you a lot.

+1 on above. It seems you've replaced everything else.

Cool, I have 3 Iacv's I bought from a salvage yard for 2 bucks a peice I'll try swapping it out. I did unplug that Iacv and it idled up.. I do kinda hear a little sucking sound around the Iacv vacuum line. Also, I found out last night I need to clean my throttle body, getting off the highway my throttle body butterfly got stuck at 2500rpm I had to smack it with a wrench to get it to return to normal. So, I'll clean the throttle body and try another Iacv and check for leaks in the Iacv hose. I'll keep you updated.

I have two in the transmission that on a Oscilliscope seem to be reading fine. I checked them when I replaced my transmission and clutch, about a year ago.

How on earth does a throttle butterfly get stuck so hard, that you need Guerilla tactics to free it ?
Unless of course it twisted in the housing because the scres locating it on its shaft came loose...

I took off the throttle body last night and it was pretty gummy and nasty. I scrubbed it with 3M throttle plate cleaner. Lubed up the linkages and cable, took it for a spin. After a 3 hour cruise, there is no problem now. I do believe it is fixed. Thanks for the assistance guys
