I just got mine recharged... its kicking on and off... what is the correct pressure for the a/c? Also I have the PFC and a FMIC. Thanks,

since you have a 93 i am asuming you converted to r134a. look at the top sticker underneath the hood. i believe it is one pound of R12 so when u convert you should fill about 80-85% of the R12 recommendation. the reason is beacause R134a runs hotter. i dont remember too well but i believe you should fill alittle less than one pound. also too much freon can be worse than not enough.

Also the compressor may cycle if it's hot outside as R-134a has a higher condensing pressure and that causes the compressor to be cycled on and off as the high side pressure goes over approx 350-375 PSIG. It is the high side pressure switch protecting the compressor. No big deal, I suspect the 94 up cars have a higher high side pressure switch rating. But all things being equal, that will make the compressor last longer.
