Converted my AC to 134a a week ago (85 442, 65000 miles).
New Delco compressor, orifice tube, accumulator. Changed the o rings.
Pulled and held vacuum. Recharged Freon and drove for about a week. AC blows very cold. Pressure is 35 low, 150 high side. Outside temp about 70. I noticed the compressor rarely cycles off at idle. Quick cycles while driving. Is this normal for this system? No icing or anything unusual.
