Bought 02 S80 recently 103K mi. Runs great, however, every so often the engine sputters whenit is idle (eg, stop light). I put in neutral, rev a little, and the sputter goes away. Other than going in for an outright tuneup, any ideas what might be causing this?

 

Make sure the throttle body is being cleaned as well and that should fix it with the tune up.

 

Thank you. Will do.

 

Let us know how it goes.
