Answers :

I bought a 2004 aveo with only 49 miles. I've had several issues with it. Changed timing belts twice.one due to Thermostat housing broke. couple Wheel bearing. Struts. Cb shafts. Etc. Recently I been experiencing high idling at start up and clutching. . Changed IAC. It didn't help. Today high idling become constant. I'm not good with motors but There is a silver bubble tube that connect to the manifold ? in the back of the motor to something near the IAC. it was cracked but it broke today causing the constant high idle. I don't know how to add picture to post but hope this helps someone out.
