2002 zr-2 just started noticing this weekend bc it was time for ac where i live. when accelerating and going up hills the ac almost stops blowing, guessing this could be a vacuum leak? dont even know where to start. all the lines i see up top look fine. i am also exsperancing over heating issues while at high rpm, like going up the mountain. dont think that has anything to do with ac though but thought id mention it.
