Q: 1900 RPM at startup for several minutes

asked by on February 27, 2018

Preconditions - WRX 2017, 15K miles on it - I changed my oil, added a quart or two too much. - noticed sut/white smoke from the exhausts indicating I had too much oil -Noticed after 10 miles and took out the extra oil. //////////////////////////////////////// Steps for the last week - turn on car - note 1900 RPM on start up for about 5 minutes - note drops to 800 - 500 RPM

////////////////////////// Odd sounds - it's a boxer engine it's hard to tell honestly especially since I went from 10w30 to 5w30 oil. ////////////////////////// Expected Behavior - I normally see the RPM close to 1000 even in cold temps I don't usually see it more than 1500

My car has a manual transmission.
