What engine do you have?

Ask Your Own Chevy Question
Customer reply replied 6 months ago
It is an 8 cyl. Not sure. Whatever they put in the 2004 Chevy Express 2500 van. Standard engine. It has been great and still runs good after awhil of the stalling symptoms.
Chevy Mechanic: Dan, Technician replied 6 months ago

Since the check engine doesn't come on I suspect you either have a dirty throttle body or dirty/failing idle air control valve. I'd start by cleaning both which you can do with throttle body cleaner and a rag. If that doesn't then replace the idle air control valve. Only other thing that crosses my mind is a vacuum leak but that would usually turn on the check engine light. Here are replacement instructions for the idle speed actuator, let me know if you have questions. Thanks.
