Hi everyone, i have a 2001 Hyundai Sonata, few months ago the A/C compressor leaked and not working any more. So i replaced almost the entire A/C system, the condenser, A/C compressor, the dryer, and expansion valve. But when the car is cold i cant turn the A/C on, it slips and shuts down the engine. Then the A/C would runs after a good 30 mins of drive, but when i switch to park, then the car rev up to almost 1000 rpm sometimes a little bit above it.
Any suggestion and help would be appreciated. Many Thanks!

It may be a pressure problem if there is too much pressure in the system the compressor would be harder to turn, how much refrigerant was added to the system you should check if it is within the manufactures prescribed recommendation?

Thank you very much for your reply.
