The AC in my PT Cruiser stopped cooling property and the engine jerks while idling when the AC is on. While sitting idle at a light it sprayed something out from under the car. The pressure gets really high. I live in Texas so it's HOT in the summer & you really need an AC. This has been ongoing for 2 years. We've replaced parts, had it serviced and it still is the same. I have read online several pt cruiser owners having the same issue.
