Thanks for your consolation Neil!

I've been out of town the last few days and haven't been near a computer...

I have two 300e's , one is a 92 and the other is an 89 (both M103). Now that the car has been sitting for a few days I'm going to pull out a bunch of parts from the *working* car, drive around until the problem manifests, and start swapping things. I worked in an auto parts store for a few years back in highschool and saw people spending lots of money parts they didn't need. I just can't get into that rythm with this car, especially since the dist cap is pricey. People would get new batteries, remanufactured starters and alternators and return their cores. We had a bench tester and probably 50% of the cores were in perfect working conditions. Dist caps can last a long time, so can wires and plugs (besides, I just can't see those causing this problem).. I might throw a new rotor in there, and maybe a fuel filter.

I do believe it is a fuel starvation issue, but not positive. I just received a digital mutlimeter (DMM) with an interface to my laptop. I'm going to connect the DMM to the idle control valve, temperature, EHA, and CIS-E diagnostic port and observe/record the various values and see how they change when the problem appears. The next diagnostic I'll be after is fuel pressure, though not sure of the best approach there...

Should take a few days to find the time and get the diagnostics set up.
