Default When I push in on the clutch my car dies...

This has happened several times in the last 6 months. It doesnt happen often but I dont think it should happen at all. Today I was coming back to my apartment after school and was getting in the left turn lane. I was going about 65 and I pressed in on the clutch and the rpm fell and then it died so I let out on the clutch and it started back up so I pressed the clutch again and it stayed running. I dont know what would cause this. Sometimes it will start to die when I press the clutch, you can see the rpm fall to about 500 and then it spikes back to 1500 and then down to 1000. It only happens if I am slowing down too, never when I am shifting gears. So im lost here.

I'd clean the IAC valve and go from there. When you press the clutch in it just seems like the rpms fall off as fast as they can right?

Its a great problem did it to me again tonight kind of bad when you are coming up to a red light and you lose power brakes. I think i needed a change of underwear after that.

Yeah we did it after I changed my intake and it was holding steadt pressure, there was no signs of any leaks. All this started before I changed my intake amd for a while it never died and then started doing it again the last 2 months. Like I said it doesnt happen often, just at the wrong times, it is only when I am coming from a high speed stop, When I am on campus it never happens, slow speeds through there, get on a highway doing 60-65 and boom thats prime time for it to happen.

I would really clean the crap out of the IAC valve, check the throttle position sensor to make sure it's still within spec and pull the codes. I had this problem a long time ago and I threw a bunch of parts at it and it took care of it.

I changed the positive and negative battery cables, fuel pressure regulator, map sensor (on my 88), throttle position sensor, plugs, and the idle air control valve. I didnt know what I know now so I probably replaced a part or two that I didn't need. How do you battery cables look ?

They look ... dirty.... the terminals are clean and have a good connection. They wires just ave 15 years of dirt on them but I have rubbed them down and seen no wear down into the wire. I could replace them, probably wouldnt hurt but. I could try the IAC as well.
