If the vehicle will stay running with the gas pedal slightly pressed, its most likely a problem with getting the correct volume of air into the engine at idle.

Mitsubishi parts look up doesn't show an idle air control valve. It looks like the throttle body is electronically controlled (no throttle cable or idle air control valve)

I would try cleaning the throttle body.

Mitsubishi Endeavor LS How to clean throttle body can

stick or auto you have to be specific here ,if it is a stick then your syncros sound like they are going bad ,if it is an automatic, then change it

kindly clean your throtle body first then fuel and air filter checking,replace if necessary..

Hello angel 003801, if the car was running rough, and had acceleration issues before you changed the throddle body, I strongly recommend you get a new air filter. Many people are unaware that the air filter is like lungs to your engine, your engine needs a good mix of fuel and air to perform at it's peak. Also, most 10 minute oil change companies do not change the air filter, at best, some of them may take it out, hit it against something to clean some of the dirt out, and then put it back in.

If the engine seems to run better after putting in the throttle body I would still change the air filter if you haven't done that in a while. Also, make sure that the throttle body is mounted securely with no leaks, look around the area of the throttle body and make sure you didn't accidently knock of a vacuum hose, ( vacuum hoses are very small, usually black hoses, and there are several in the general area of the throttle body. If you should find a small hose that has one end that is not hooked to anything, look around for a small nipple that it may have come off of.

Thank you!

unsure if this is petrol or diesel model. check basics first,air filter not clogged,sparkplugs not sooted and gaps burnt wide. if it is a GDI V6 model,thay have common fault with dirty throttle body(TB) and air mass unit,causes rough idle and gets worse over weeks until it doesnt improve.this can be easily fixed by cleaning with solvents available for air flow sensors and tb's. if engine has plastic cover,remove this to access TB

My 96 Pajero SWB 3.0 would loose power as soon as i accelerate. It feels like the spark plugs are miss firing or if the engine was flooded.

I did a general service which included oil change, oil filter, fuel filter, air filter, spark plugs i checked my O2 sensor, dissembled and cleaned throttle body and sensors. Cleaned air intake sensor as well as the distributer etc.

Problem not solved, still loose power when i accelerate....can it be something wrong with my ECU??

My A/C control isnt working at all. Found a 15Amp fuse that was blown but when replaced it shorts again. Where can i get a wiring diagram of the heater/a/c system for my vehicle model?

AutoZone has this in their online guide here.

I said i need an airg cause my boyfriend keep one texting me brus

Our 2001 mitsubishi montero xls ran hot and blew a head gasket.We just got it back and it rus great but has a little shimey or puttin when we are sitting at a light,as if it is idle to low.Put it in park and it runs smoother. Idle sensor or throttle sensor got damaged from the heat? Not sure...just thinking out loud! Any other suggestions?
