Running rough

96 ti, m44. Engine idles perfect when cold but as soon as it warms up it starts sucking a ton of air in the pcv valve and runs very rough with a weird pressure equalizing noise when shut off. No cel, no codes. Checked for vacuum leaks and found none. Anyone ever encountered anything like this?

It was a bad ccv valve that was causing all the issues. Replaced with oe and now it runs great.

glad you were able to fix it. I found that the Febi brand one isn't as good as OEM.
