2000 S40 High RPM
 

Hi i own a 2000 s40 and when i started it from cold I see that the RPM is little bit above 1K RPM. I think isn't normal, what can cause this?

Did it stay there even when it warmed up?

this happened to my first car which was an s40..... does it start ok?

RE: 2000 S40 High RPM
 

when it warmed up or after run it for about 10 minutes the RPM go down for about 700 RPM

Most of times start ok, but sometimes like when the night was cold the starting don't fell good, in some ocasions i have to start it two times.

I would clean the throttle body and check the coolant temp sensor.

Already clean the throttle body , but the problem still. Maybe it's time to change the spark plugs.

When it is cold the idle will raise for about a minute or two then drop to normal.

You might also want to check fuel pressure and see if it drops all the way to Zero when shut off.
