Re: high idle
When you turn the a/c on the compressor comes on which draws power from the engine. Therefor the engine has to work harder. Thats why the revs go up a little.The computer will regulate the compressor going on & off while the a/c is on. So your revs will go up & down just a tad as the compressor go's on & off. As far as being low on gas I dont think it has anything to do with it.
