Need a Spot
Hello everyone.

I just bought a Pajero V6 3.0 6G72. Im having problems now with the fluctuating idle. I have cleaned the throttle body, idle speed controller, air flow sensor(just after the air cleaner). changed spark plugs,changed fuel filter, changed air hose, adjusted engine timing to specs. and still im getting fluctuations on my idling. i even have it diagnosed at the dealer with their Mut-1 or Mut 2 but to no avail.

what could be my problem?

Can anyone please help me???

Aldee check the big air hose from the air cleaner to the throttle body for leaks. If its cracked or has small holes it'll mess with the idle. If you have a spare just swap it out. If thats not the case, check you O2 sensor, sometimes it has a faulty connection.


always working

Also check to see if your EGR valve is stuck open / plugged with carbon build-up. That can cause an erratic idle.
