Rough idle at stop light

Thank u ...could it be Somthing els . I replaced and checked vacuum lines. I should have mentioned this. Also idles rough after I drive it for a while then at stop signs

Can you elaborate on “rough” like it’s it dying out or is it just shaking??

Goes from 800 rpm to 600 then back.

and when u give it gas it’s fine? My gut says change your PCV valve. But I do know It’s the easiest repair ever just YouTube it. The part is cheap and it should be done Anyway. Do you keep regular maintenance?

Yes .....i will check pvc agian. Thank u

Don’t do it again man. Fuel pressure regulator?

I will check it out thank u

Scan for codes. Might just be overdue for a tune up.
