thanks for all the help
As stated above make sure you pull a vaccum. I just did this last weekend on my 94, here are the steps from my manual.
1) Pull a vaccum takes about 2-3 min to get down continue to pull vaccum for 10 min.
2) turn off vaccum pump and left sit for at list 5 min (I waited 10) make sure your vaccum stays and does not drop, this would indicate a leak in the system.
3) If everything is good the pull the vaccum for an additional 10 to 15 min.
4) Add your can of R-134a OIL first (10.5 oz can = 8.5oz oil and 2oz freon)
5) Add your freon (ours took 1 can of pag oil and 2 cans freon)
6) Make sure to watch your gauges as you are changing you do not want to over charge.
You may need to bypass the low pressure clutch cycle switch to keep the compressor turning.
