idle problem I neeed HELP !!!

Tried that multiple times… Seems like it helps for a few minutes to even hours then eventually gets crappy again within 48 hours. Any other options I have?
Also noticed If I clutch in while coming to a stop the rpms sorta hesitate to drop and stop for a few seconds at 2 seperate locations before it sets at normal idle. When idling is in crappy mode I notice the car bogging bouncing during acceleration or while cruising at low kms in 2nd or 3rd gears.
