strange idle 940

Thanks for the reply. I pulled off the IAC- clean. Cleaned the throttle body, it wasnt too bad, but couldnt hurt. Started up,. What i noticed was as the engine warms- the rythmic miss or stumble at idle get faster and faster. So when just started from cold-runs fine. As it warms the rythmic miss changes from every 15 seconds to every 8 seconds. Seems to stabiize at that rythym.

Would this be o2 sensor? What in the idle system is temp related.

the engine never dies, just does this odd stumble/miss or hesitation.

This car is Bosch.

Thanks again,

Andrew.
