I just bought this car and did a bunch of work under the hood like timing belt, pulleys, tensioner, seals, water pump, oil change and of course coolant flush. Then I got some erratic idling and some cel codes like 3,4,14 maybe. I cleared them and it drove great. Now the idle still fluctuates about 1000 rpm's off of idle. In H and F 22's there is a bleeder valve that you open after the cooling fans have cycled three times at idle. There is no valve that I can see to burp this one.

I think it is the IACV that is acting up because it only does this idle when warm. Now If I run some seafoam through the intake off of the booster hose, I could possibly clear it up but I think it is a blockage in the cooling lines preventing it from functioning properly. What do you guys think? Is there a way to burp the cooling lines to the IACV on a CL 3.0?

I do not own a manual yet as I just bought the car yesterday. Tomorrow should shed some more light upon this problem and ceratinly will hold a solution. Any helpful input or links would be greatly appreciated. This is my first J motor. I am quite well familiar with the F and H motors as well as B and D.

Respectfully,

Peter
