JA: Sometimes things that you think will be really complicated end up being easy to fix with Volvo. The Volvo 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: No codes. My mechanic is going to be replacing all the belts soon and he will look at the plugs. It doesn't idle rough and there's no check engine light on either.
JA: Spark plug problems can be challenging. So many causes, some simple, some complicated. Fortunately, the mechanics we work with have tons of experience dealing with all of them. Are you hoping to fix this yourself?
Customer: No. Just looking for second opinion.
JA: OK! The Volvo Mechanic will help you with the diagnostics so you are sure to get this fixed right. Is there anything else important you think the Volvo Mechanic should know about your Volvo?
Customer: It's been trouble free so far.
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Volvo Mechanic about your situation and then connect you two.
