I have a 2008 Outlander sport SE 2.4L with 110,000 miles. It idles smooth in park and neutral 600 rpm but when I put it in gear the car shakes. I have replaced the spark plugs, pvc valve, air cleaner, cleaned the throttle body, checked the air flow sensor which is clean. This model does not have an idle air control valve like other models. It does have a intake pressure (map) sensor MN153281 but not sure if it would have any thing to do with idle speed. This seems to be a common problem with Mitsubishi from what I read. How do I fix this problem?

 

I have the exact same issue. Same parameters too! Have to put it in Park or Neutral at traffic lights.
Another problem with this thing!

 

Have you both put an OBDII reader on your vehicles? If you have, what did the reader tell you? If not, that's the first thing I'd do. If it doesn't indicate any codes, good for you.

The second thing I'd do if I were both of you is put some dri-gas in the tank and see if that helps after a quarter tank gets gulped down.

Then I'd be looking at spark plug condition and the ignition coil wires and the ignition coils themselves (four separate coils, right?), which is an easy task on a 4 cyl engine, I hope.

(BTW, did the '06 and '08 2.4l have CVT or auto trans?)

Good luck. I hope both of you post the final fix.

 

Mine is a 2010 and it has the CVT 2.4.
Thank you for the suggestion. I will try that
