hesitation/slight bogging

[93Lx]

First off i have a jdm h22 5 spd with a p28 ecu. When i drive at normal speed 50-55 i feel the car hesitate and slight bogging. And when i come to a stop my rpms drop around 650-700 and it sounds like it's about to shut off. But when i tap the gas it goes up for a few seconds in then comes back down. I thought it was the egr but i was informed that i should have that problem with the p28 ecu so im stuck...

Check idle adjustment.

Check idle adjustment.

i do need to adjusted it but that will cause the hesitation and slight bogging

i don't think it's tuned but i know it has a h22 base map.

might be a vacum line, then can cause alot of idle problems and bog you car down. Could also be a stuck pcv.

check all the vacuum lines by squeezing them off one by one with needle nose plyers. see if the idle changes on any of them. next check the pcv by pulling it off the valve cover and feel for vacuum, if there isnt any, you could have a clogged passage and youll have to clean it. also when you pull the pcv see if the rpm changes, if it doesnt and there is vacuum at the pcv, get a new pcv valve, there super cheap. hope this helps
