idle atfer warmed up

Post by **jcdavoin** » Mon Mar 22, 2004 8:48 am

I own a 95 J30 with 106Kmiles on it.The car always starts good. Warms up good.Idle speed is good for a while (after car is warmed up).BUT, if I were to stop the car and let it sit for 15 min, the idle speed gets messed up like its missing cyl or something.The coolant circuit has been flushed, the temp sensor changed, air filter, Spark plugs are new(NGK).I even swap the MAF with a used one and still the same deal.I could drive the car for hours, as long as I am moving, it ildles good.I am running out of ideas.

I appreciate the help.

Well, I had the O2 sensors replaced (bought them from Scottsdale) and...idle problem is gone...Just thought I would let you know.

Have you reset the idle speed hot per your FSM? What is the IAC duty cycle hot?
