I have a rough idle and feels like engine is going to die when i idle for a long time. This increases with any additional load into the system (like AC, Headlight, Radio etc..). This happens in all modes (park, drive, Neutral etcc) and engine is idling. No problem whenever Rpm hits above 1000.

I suspect a stuck open EGR valve. I am having very hard time finding the EGR valve and nobody is giving any clue about this particular model. I would like to take out teh EGR valve and clean it.

It appears that this vehicle doesn't use an EGR valve. That's why you can't find it.

Thanks a lot. That gives me more confusion. Do you know what else would be the problem.
I checked IAC valve and it looks like it is working. When i turn the key to ON, I could see it briefly retracting and coming back.
If i remove a vaccum hose, the engine rpm goes high, so i think the intake pressure sensor also working.

Any advice will be very helpful..

Thanks a lot..no where in internet i could find this NO-EGR system in stratus. Thanks again.

You may have a bad IAC ( idle air control) but try cleaning the throttle body first. Remove the intake snorkel, have someone hold the throttle wide open for you and scrub the back side of the throttle plate and surrounding bore with an old tooth brush and some carb cleaner. Be sure to spray some into the small holes next to the throttle plate. That should help stabilize the idle. If it still has a problem, replace the IAC.

I already cleaned the Throttle body and IAC valve.

I took the IAC valve outside when engine is not ON. IAC valve is opening briefly when i turn the Key to ON. When i remove the IAC valve electric connection, Car doesn't start. Does it confirm IAC valve is working?

Working and working properly can be 2 entirely different things. I'm not there to examine it so I can't say one way or the other.
