1984 500sel idle

Hello all, I've done a search and now I'm totally confused [:(] I have a 1984 500sel, the idle "stumbles" most of the time when its at op temp, the oil gauge also jumps around while its doing this... thought it was due to rpm dropping then going back to normal but after reading some posts I'm not sure now... something about it being tied into the idle circuit. Anyway it also stalls sometimes when you come to a stop. From what in can figure out I need to clean the air valve and check the elec. box for cracked or cold soldier joints. The elec box is the easy part once I figure out where it is as I've fixed many "junk" Volvo overdrive relays in the past. I guess I'm asking if I'm on the right track and is there anything else I can do?

Thanks in advance for your help:

What shape are your rotor, distr. cap and wires in? What do the sparkplugs look like? Has the timing been checked? Any vacuum leaks or leaks around the injectors? How old is the fuel filter? If fuel related, adjusting the air/fuel mix should take care of the stalling problem. It would help to know what you have done so far. The 'search this forum' box has write ups on all of this, including how to clean the idle control valve. Good luck.
