1999 mitsubishi montero sport. Randomly started hesitations and low rpms in gear at idle. and highway speeds dropped rpms slightly and when let off accelerater rpms drop too quick and low. Any ideas?


Engine light on? Many things can cause this. Mass airflow sensor, throttle pos. sensor, cam sensor, idle control valve, O2 sensor, vacuum leak etc, diagnosis be great. Good luck

Mitsubishi triton mn


it may require a ECM upgrade in the software
in the mean time restrict the rpms between gear changes
for example accelerate in first ti around 3000 rpms and slow down the selection and keep the rest of the changes around the 2500-3000 rpm range
naturally , the harder yo rev it the longer it will take for the rpms to drop
just as a point of interest how did you get a brand new car that is 4 years old ?

Problem with electronic throttle control maybe. Any light's lit on the instrument cluster or messages engine power reduced . Could be a sign a position sensor is going bad . The gas pedal assembly has to sensors as does the throttle body . You could try cleaning the throttle body bore . Having a qualified repair shop hook up a diagnostic scan tool to view sensor data would be a good thing .

The EGR valve sticking, loose wires, bad ground connections, dirty connections, fuel pressure dropping out, vacuum leaks, or any combination of several of these at about the same time.
