Default MUT3 in Perth for rough idle after intake clean.

Hi everyone

I just had some work done on the new Pajero. After buying a Platinum with 175000 KMs I though it would be a good bit of maintenance to do.
I got the work done at Vehicool in Canningvale. It's a great workshop and I would recommend. I got the valve clearances checked, intake cleaned, transmission flush and both brakes skimmed and new front pads.
The intake manifold was really bad, good 5mm of gunk in some parts. The intake valves were apparently a bit tight too. Lastly the transmission fluid was pretty dirty too.
Super glad I got this work done. In the last couple of days the idle has been pretty rough. It makes the whole car shake. I noticed it seems to be a bit better when out of gear.
I've read about the injector relearn being needed after clearances and intake clean to complete the job. I feel this has merit as I've changed the way the engine breathes now. Or it's the engine mounts.
Does anyone in Perth have a MUT3 that can do these relearns? Or do I have to go to the dealer? I'd love to trade a box of beer for a relearn before I go down the engine mounts road.

Cheers Nuggy

I have the same issues, after I cleaned intake manifold and transmission fluid change. Car had done injector relearn still running rough. Itís rough idle only when the engine is cold but when itís warm, car is perfect or it could be dirty transmission fluid.
Is your car running rough idle when engine is cold?

Kimmy,
Yeah I did notice it got a little better as it warmed up. I've only bee able to drive it down to the shops so not really getting it to operating temp. I will take it for a good drive on the weekend and check.

I forgot to mention the car had a bit of a low rough idle before the intake clean. It idled at about 650 which I think is a little low. It's noticeably worse now.

How did you do the relearn. Did you go to a MM dealer for it?

Yes, I took the car to MM dealer do relearn.

The cold weather will effect car running rough idle, especially the first start in the morning
