Hafadai Posted October 7, 2019 Share Posted October 7, 2019 My 2015 Mitsubishi Outlander Sports vibrates and the RPM goes up and down. What is the problem? Link to comment Share on other sites More sharing options...

Jim K Global Moderator Posted October 7, 2019 Global Moderator Share Posted October 7, 2019 Could be a vacuum leak, EGR system malfunction, oxygen sensor, fuel injectors, fuel pump, spark plugs, mass airflow sensor, throttle position sensor, etc. Your friendly neighborhood mechanic could tell you. Assuming your CEL is burning bright so any AutoZone, etc., could also look up the code to narrow it down. Link to comment Share on other sites More sharing options...
