The loping probably indicates that the idle is set too high. I rarely 
see dirty injector problems with these, so I suspect the cause is 
elsewhere.

Start with the usual suspects: dwell, timing, & valve adjustment. If 
those seem fine, check the compression, just to make sure.

Sometimes the electrical contacts on the plugs to the injectors get 
loose and have to be released (gently!) from their holders and 
squeezed ever so slightly so that they make good contact again.
