Rough idle
Hey y'all, I got a 2008 Lexus is 250 that kinda rough idles (?) the best way to explain it is that sometimes when I come to a complete stop my rpm's will go
Down to 500,vibrate and then go back to a normal idle, on top of that sometimes when I'm in reverse idle or drive idle it will idle rough but only when the car has been turned on.I've narrowed it down to being an airflow issue with my scanner. Also with previous issues my car would shut off right after being filled with premium gasoline or wouldn't start at all unless I gave it gas but I took it to get it fixed where they replaced some hoses, cleaned my CATs and made sure it was running good. Recently I had a code pop up for a purge valve which I replaced with a new duralast one which made it better but still hasn't solved it. I feel I should note on the wire connecting my purge valve kinda looks a little jank but if you guys have any ideas or need more info lmk and I'll answer as best as I can
