Thanks RonD!
Thank you kind sir! For the welcome and advice.
I pulled the throttle cover off and inspected the vacuum hoses the I had replaced when I got the truck last year. They were all solid and intact. I removed the intake tube to check the filter and spray some throttle body cleaner down the opening when I noticed the flange wasn’t fully closed. Then I noticed that the throttle stop screw was keeping the flange from closing so I unscrewed the stop screw about 1 full turn and Voila! Problem solved. The truck idles @ 1000-1100 rpm cold and 750-800 warmed up. Just like magic.
No vacuum leak but too much air. Maybe I’ll get better mileage too. 😊
Thank you again for the advice.
