68 280sel Stumbling issues

I have had my benz for almost 7 years now and have had a problem in the last year or more with it developing a stumble at low rpm under load and high rpm before shifting to the next gear. I have installed a new electronic ignition from Crane Cams new cap and rotor the wires i replaced 3 or 4 years ago and the plugs are all new as well however the problem persists. I took it to a respected benz shop here in portland, since i have little time to tinker with it with my college load as well as not having a place to work on it. This shop said it was a failing oil ring, however my oil consumption is very low for such an old car and the only time there is blue smoke is when it is cold, and it is minimal at that. I am at my whits end here since i have gone through everything even the fuel filters. Does anybody know if this sounds like a fuel system possibly injector, injection pump, fuel pump, or could it be a bad coil(which i replaced 2 years ago) or valve adjustments? Any ideas would be appreciated as I am quickly losing the joy of driving my baby, and that is unacceptable [:(]
