Heyyyy -genius! If you turn off the AC there is still a low-grade 'chuntering' but that completely gets rid of the cycling... we can just go through some causes of the rough idle at the shop; I was dreading it to be something in the transmission!

The AC was never all that strong since I got it; changing the gas really helped but perhaps the compressor/ system was faulty the whole time. I also need to address the cracked expansion tank today so I am taking money with me
