new idle problem

[1997eclipse rs]

i know i have a post on this already but its got worse.
now when i start my car it reves between 1000-3000 when im letting it warm up then about 5 min later itll drop to about 300 rpm and act like its going to die sometimes it does. as i drive it through the day it will randomly rev up and continue to act like its going to die and sometimes it does.

this is a really annoying and i just want to fix it any advice or tips will help just let me know thanks in advance!

might be your idle control sensor. I sorta had that problem to. also check spark plugs. and your fire order!

if you're check engine light is on find someone that have a code reader... it's always nice to have your own reader... if you plan to keep your dsm it's a smart investment.

Try replacing your throttle position sensor, and if you still have problems try cleaning or replacing your idle control motor/ valve

Mass Air dirty, replace O2, cam angle sensor out or dirty or backwards, manifold leak?
