My part will be at the Chevy dealer on Friday morning.. Meanwhile I used electric tape to hold it together til then, Thx again

Is there any way that you could post a picture of this part, and where it is on the engine. I have a 2003 alero 3.4L and I am experiencing he exact same problem. I have changed or inspected everything else you and others have described to no avail.

As this is my wife'* car she is not only insulting my car savy for not having fixed it yet, and growing increasingly irritated that she has no car.

Thank you for chronicling your problem.

3400 alero is not the same evap setup. you should start a new thread with your exact symptoms and we can help you better
