High revving
Hello all,
Been having problems with my '05 monte ss revving really high on cold start. Its gotten as high as 2500 rpm on idle. Turning off typically doesn't help nor does hitting the accelerator. Driving will usually bring it back down to the 700 rpm range where it typically idles at.
No codes so I'm wondering if it's a vacuum leak? Dirty IAC valve? What would be the most common thing I'd wanna check? 🤔
