82 300SD AC Comes on only after "gunning it"

To get my AC to come on I have to give my car a good rev up. If I take off slow and drive slow it will stay off the whole drive. From a cold start it I gun it it will come right on. Cold engine and all.

I jumpered the two switched, low pressure and the one by the accelerator, I changed relays, topped off the R12. Once it comes on it works fine.

I drove home the other night and never accelerated forcefully and it stayed off. The next morning I took off fast and it came right on. Now I just turn it on by gunning it right after taking off.

Any ideas?
