Default BBK throttle body

I took my throttle body, cleaned it real good, took out the IAC and throttle pos, sensors, cleaned those. I noticed 2 tubes that have been cut off, i blew threw and they are connected, blow in one ais comes out the other. What are they and is can that cause the car not to idle consistly.

Those are coolant passages to keep the TB warm. The do not affect idle.

Oh ok. I guess they by passed them when they built this car. My engine light comes on when it idles down real low like around 700. As soon as i keep i rev'd at 1000 the light goes off......

Most likely your iac or tps is faulty.

750 should be your baseline set idle
