I have a feeling mine is slightly low on r134, I'll probably top up at the same time. Only problem with mine is at idle ons crazy got day it is not that cold. Still cool bit not nearly as cold as when the car is moving and the revs are up

Thanks, I look forward to it.

No doubt your underdrive pulley is affecting that as you mentioned earlier. Practically every car I've owned drops cold air at idle and increased revs and more air through the condensor brings it back to life. Think I'll check out my other Yaris and minvan as well. Gotta make those gauges pay for themselves. LOL.

How much does your A/C affect idle on the 2ZR? Mine seemed to labour slightly, until I removed a bit of the refrigerant. It still slows a few rpm when I engage A/C. I'm getting the impression that A/C systems are more power-robbing than I had initially thought.
