Concerning romp?

I noticed tonight that after it warmed up and i drove to a friends went inside for maybe 30 min then when i left engine was still warm but upon firing up the idle surged from 500-1000 like a up down up down up down i gave it gas it settled for about 30seconds then did it again. It is not cold right now only maybe 60's outside but i brushed it off until i noticed it trying to surge at a light after i had been driving for about 15min any suggestions where i should start looking?

Runs fine other than surge never noticed it before it has always been real steady on idle.

Im not pulling my hair out cause its not a major issue i just want to make sure it does not lead to something worse..

Has it been giving you any kind of trouble starting when its cold???
Not to scare you but about 2 months ago mine did this to me on a few occasions, then 1 morning my truck wouldnt start no matter what I did..my IDM took a s**t on me and must have fried out. Mine was getting harder and harder to start though.

When you hear people talking about their truck having a cold weather "romp" what they're describing is the engine running on 7 cylinders (#8 fails to "fire" because #6 took all the HP oil that powers it).

That's not what you have - right? You're describing a "wandering" idle rpm I'm thinking....

So, this could be a LOT of things, BUT the good news is, it's a piece of cake to diagnose with a good scanner. Find someone, with the right scanner (forget AutoZone or any of those guys or any of the cheap hand-held OBD-II readers your truck needs special sw) and you'll get an immediate answer as it's doing it. I agree, before it gets worse, find out what's going wrong

You could give this a shot first though, next time it's doing it, open the hood and unplug the ICP sensor. It's kinda a long-shot, but it's a Free test! If it cures the problem, and I'd confirm this by seeing it happen several times because ICPs aren't cheap!

I have the same issue with my 02 Ex.I have a new number 8 injector 7 new o-rings,new glow plugs,v/c gaskets and harnesses.This was done for a oil consumption problem.I have no codes and put in a new icp I had,new fuel filters,took out my tune and went to stock,switched oil grades and went to synthetic and still have the same deal.My next step is to take home and ids and see whats going on while driving.My truck does it hot or cold but not all the time.
