Ok, my $.02 here. I "had" the same problem until I set the timing and the fuel mixture just right. Runs like a champ when warm. I have an 83.5 1.9l and have had the same problem for awhile. I could get it to run fine without the A/C, but when I had the A/C on, she just didn't have the horses to get up and go from a dead stop. I set the timing a few degrees ahead and tweaked the fuel mixture at 2000 rpm and at idle till they were just right then tweaked a little more. So far so good. btw, I used my oxygen sensor to do the adjustment. Not the most accurate way, but the most economical.
