I finally decided to go for R 134a retrofitting. I believe I had a very slow leak in the system while running R12 (shops could not detect one) but my compressor would begin to cycle rapidly and cooling would be unacceptable. I bought a new compressor from John Hervey at PF, and I followed Bill Robertson's retrofititng instructions on the DMC NEWs tech page. They are simply brilliant, especially for those of us with out vaccuum pump capable of pulling a good vaccuum on the system. (bill's method uses engine vaccuum to suck on the system. I now have air just as cold as my other delorean's R12 system, and the compressor does not cycle nearly as much as it did before. I also bought R 134a at walmart for 3.62/can, this is a good deal if anyone else needs any. Anyway, My air is cool now, and that is what matters. Joe P.
