Weird uneven idle on my Gen 4

Mon Feb 11, 2019 11:04 am

Hi guys.

My 2015 Gen 4 with 75 000 km on has developed a weird idle problem.

When I stop dead at a stop intersection or traffic light the engine idles with a lumpy feeling for about 3 seconds and then goes away. Problem is that this is very infrequent and mostly random.

Some guys point to dirty transmission fluid but the oil change only comes at 100 000 km.

I have done some tests as suggested by selecting neutral just before I stop to see if it persists. But being so infrequent it is difficult to select neutral when it happens because the period is so short.

Any ideas ?

Cheers

Hi

I though Transmission Fluid interval was every 60 000km?

Mine has started with the same occasional slight variation in idle speed, I suspect the SCV (suction Control Valve) from what I have read. Min is due for 260k service in 500km, so I will be doing that first (incl new air/diesel filters) and then decide if further action is required

Maybe top up the diesel tank with some fresh juice as a start. Also make sure the airfilter is nice and clean.

Can't hurt to start with the small things.

I think your Pajero needs some fresh Barberton mountain air. I can assist with that!!
PS. All Pajeros run better on fBma

Thanks guys.

@Henk I queried this with the dealership after the 60 000km service and apparently the 2014 onwards have a high output transmission which only requires changing at 100 000km. The service book confirms this.

@CATS I will start going through those basic items and see what pops up.

@Roelf I cant agree more. We need to set up that weekend we spoke about last year to go play in the mountains seeing I cannot come in the week to discuss mining machines with your Engineer. Pity......

Cheers
