Customer Question

2002 Chevy Tahoe 170k miles engine at idle makes noise like disel engine from the bottom but goes away in gear. Thank you
JA: Sometimes things that you think will be really complicated end up being easy to fix with a Chevy. The Chevy Mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so he can help you best.
Customer: Just like I just wrote
JA: Are you hoping to fix this yourself?
Customer: Yes please
JA: Great! What have you tried so far?
Customer: Changed the oil pump oil pickup cam sensor idle control valve..
JA: Is there anything else the Chevy Mechanic should be aware of about your Chevy?
Customer: That's all so far
JA: OK. Got it. I'm sending you to a secure page on JustAnswer where you can place your fully refundable $5 deposit (plus $13 after the Chevy Mechanic responds). While you're filling out that form, I'll tell the Chevy Mechanic about your situation and connect you two.
