Recently got a 00 S40 with 140k miles on the clock.
Problem is when the throttle is blipped, the car will not return to its idle speed for a few moments, and alternates between 1500rpm and 500rpm for about 3 cycles, before it steadies itself. This manifests itself when the engine is warm.

Also, there is a nasty rumble from the engine at about 1200rpm - appears to be from the top. Could it be a stickyVVT solenoid/pump assembly? No faults are logged in memory?

Anyone been here, worn the t-shirt??

For an idle fault on one of these; start by cleaning the throttle plate and idle valve and checking for air leaks.

Rattling VVT actuators aren't a good sign either.

Thanks for that Screwloose. I'll delve into those areas if it ever stops raining here!
