Question about 2002 Mitsubishi Montero Sport

1 Answer

I have an 02 montero sports. i just noticed lately that when my heater is on and my engine is hot, it's running rough from 25-35mph speed. but then it goes away when i'm driving about 40mph. i cheked all my fluids and everything seems to be in a right level. i don't have my check engine light on, so, i guess it's not diagnosing anything. any help will be much appreciated.

Running rough after overheating


The idle is controlled by the computer, based off of sensor readings. Whenever I replace the battery in my Montero, the car won't idle very well because the computer has been reset and it has to 'learn' the environment. After I drive it for a day or two it runs fine. It is pretty simple to try disconnecting the battery for 10 minutes to reset your computer. Take it for a long drive afterwards so the computer re-learns the environment and see if resetting the computer fixes the bad idle. I would think the service engine light would be on if you had a sensor issue.

Hi and welcome to FixYa!

Yes it can be the oxygen sensor but I strongly suggest that you have a tune up too to correct the issue.

Hope this helps and thank you for using FixYa!

I have a 98 Montero Sport and to adjust the idle all I needed was a phillips screw driver. Check owners manuel for Idle speed and remember to have lights off when adjusting. Also it showed the idle range posted on the hood underneath.

Mitsu Montero Sport '02 engine stalls but not when air cond is on.


hi there. the reason that the engine idles good when the air-con is engaged is that ussually all vehicles nowadays have a vacumm advance mechanism. this is triggered mainly by a electric solenoid valve which is also attached parallel to the source supplying power to compressor. a small vacumm hose with a diameter like a common pencil or ballpen case. its made of rubber and it runs from the alternator vacumm pump then to the solenoid valve and to the vacumm advancer unit attached to the injection pump throttle. this system raises the idle a tad higher.

if your montero runs completely normal and you experience no other problems with your engine except for your present problem, then the solution is just raising the idle a little higher. if your montero is equiped with a RPM guage on the dash, try adjusting the idle to around 800 rpms. it would be healthier for your car if the idle raises a bit when you engage the air-con because this would compensate for the added load on your engine.

hope this helps.

02 Mitsubishi Eclipse heater gets hot only when in motion


Does your engine temperature guage read normal? Have you checked your coolant level? This can be the result of a partially seized thermostat... there is also a valve in the heater core lines that can seize partially closed. As the engine speed increases, the water pump can force more water through the partially closed component.
