I'll attempt to make this short. Truck was previously converted to r134. Compressor bearing went out so I replaced compressor and charged ac myself (r134 cans from autozone without stop leak). Had some issues with low pressure so took it buddies shop to be properly charged. At idle, the over pressure switch would trigger and blow freon out the back of compressor. Decided to bite the bullet and replace everything. Another new compressor(ac delco), condenser, orifice tube, all lines, dryer, belt, belt tensioner and fan clutch. Flushed evap core. Took it to shop for the freon, still at idle it over pressurize and blows out the back if the compressor at the relief valve. Any help would be much appreciated.
