Ok, so I still haven’t fixed the “vacuum leak” (and i put it in quotations because i’m not 100% sure what my problem is anymore), and this morning when I was driving to uni my car started acting up.
First my AC wasn’t on… and I noticed that before then, my idle would be 500-600ish and ready to stall out almost every time i brought the car to a stop. It started getting humid in my car and outside was loud and smelly, so I just turned on my AC. I realized right away that the RPM had jumped right up to 1000 and stayed there. I thought to myself “okay…wtf…” So i turned it back off… down to 600… back on… up to 1000… etc. etc., to make sure that the AC was the culprit. Turns out that this happened EVERY time I turned my AC on or off…
I noticed, also, that with the AC on, the engine made a bit of a wheezing noise, and my RPM would randomly rocket up to 1900 (usually around 1500 though)… and then go back down to 1000.
WTF is up with my car? lol.
edit: all this AC on/off business was while the car was at a STOP (ie. red light or stuck in traffic)
