To have a decent a/c system on that car you need several things to happen.
#1) Making sure that the fresh air door closes all of the way!
#2) Making sure that the system isn't overcharged. (1.9-2.2 lbs on that car)
#3) Making sure that the condensor & radiator are CLEAN!
#4) Having the condensor fan run (high speed) as soon as the temp & pressure builds.
