07 c70 stumble and slightly rough idle
Help, I have a 2007 c70 t5. I have recently picked up a slightly rough idle, and a stumble on acceleration starting about 2800rpm. I have no check engine light. I replaced plugs and checked coils. Cannot find a problem. Any thoughts? I am new to Volvos and turbos. Any thoughts would be greatly appreciated.

I might go to a parts store (Autozone, Advance Auto Parts, or other) to have them check for engine codes anyway. They can be "pending" and not cause the light to come on yet, but can still be read with a code reader. I would also check your vacuum hoses to make sure they all look good, with no cracks or dry-rot.

Hey!
Similar issue, and its throwing codes for the Idle Air Control Valve and random missfires. Degenerated to the point it stalls pretty much every time it idles down. which sucks to drive.
I want to pull the throttle body, clean it, and replace the IAC module. But I cant even see the throttle body tucked up under the manifold to get an idea if I can do it or not.
Looks like the IAC is right there in front/under the intake.
Im a decent fluid maint guy but havent had great luck when tryin to pull major engine parts and replace. I just dont have the XP, tools, or garage for it.
SO Im going to start looking for a shop in the area and see if its doable.
Also thinking of getting the Alldata for this car and see what it has to show me. Anyway, thanks!!
