[sx89]

Ok so I have a 89 hatch single cam that I converted from r12 to 134. I installed all the ac parts from another 240 flushed all the lines new drier and seals. Had it working great for about a day the. The exspansion valve messed up so I just put in another evap wit valve had it working good for about 3 days when the high pressure relief valve blew. Ordered new higher pressure 134 valve and the got system filled back up and now my ac comp turns when I de accelerate. Iv played wit the amount of freon adding a lil more taking some out, doesn't seem to affect it swapped of the high pressure switch and still no change. The ac seems to be affected by rpm when ever I push the clutch in after driving a few mins the comp shuts off and won't comp back on for at least a min. I don't know Wat to check but the pressures seem to be fine. Hope somebody can point me in the right direction.
