Intermitent Rough Idle

Recommended Posts

Hello again everyone! I have to tell you -- I am completely stumpted -- on this one. I keep getting intermittent error codes P023, P025, and P083. I've changed out the ICM, checked the PCM and wiring, and checked the grounding locations. And I'm still getting these error codes every now and then. What am I missing? Has anyone else had this problem before? Thanks for all your help! Vincent

P.S. Is there any way to check the ICM to make sure it's working properly? Can auto parts stores do this check?

I noticed something the other day. When I had my air filter top cover off with the wire that is attached to it disconnected my idle is rough, check for a bad sensor there or for a bad connection there... Mike

Early on sailors navigated by the stars at night and the North star became the symbol for finding ones way home. Once you know where the Northstar is you can point your ship in the right direction to get home. So the star became a symbol for finding ones way home or more symbolically even finding ones path in life.

Grounds, connection may look good and even be good but cables degrade. I would put some temporary jumpers from the battery to crucial locations and see if it helps. Replacing the old cables would be the next step.
