My car has been idling VERY rough the past week, so bad that it starting to die at stop lights. It would start back up, but only keep going if I was on the gas. I ended up freaking out and taking it into a local shop. They told me my PCV valve needed replaced, and that it had a misfire as well as the oil cap wouldn’t even come off when it was running (don’t know if that’s a thing). So I agreed to have it replaced. I went this morning to pick it up, and even though they said it seemed to idle a bit rough at the start it seemed to be OK now. Well it wasn’t I drove one mile to my work and it was idling again all crazy. I turned it off and back on and it had a tough time starting (but did). And the very bizarre thing is my A/C no longer worked and I ended up with a “stability control error”.
I promptly ran it back up there and talked to them. They look really baffled, but did mention if a code got flipped in some cars the A/C no longer will run. I have never heard of that before, but I guess if it’s true maybe it relieves load off the engine?
Anyhow I am sitting here a bit freaked out as I am broke and I have no idea what they are going to say. So I wanted to ask around and see if the rough idle, starting symptoms line up with a bad PCV valve. And if anyone had heard of the A/C shut down situation…
Thanks for the help!
