ps,

I hope you don't think I'm picking on you or anything, but am I correct in remembering that this car was an original R12 car converted to 134a? If so, if you want to improve the performance of the a/c system, there's nothing you can do that will improve it as much as reverse converting.

You are in a TOUGH a/c environment, and a converted system is just not going to perform like an R12 system. From the results of some of your earlier posts where you gave your temperatures, it's obvious that you did a great job in the conversion, but you are REALLY handicapping yourself.

If I remember incorrectly about the conversion I apologize.

Best of luck with it.
