Hi everyone.
My Dads beloved pajero is driving him up the wall with poor tick over.

Starts spot on and drives fine. When up to temperature when you come to a stop it idles poorly like its going to cut out, but then recovers.

We know its a fly by wire which i believe can be a pain. Checked all the obvious and serviced regularly. If it was the TPS i believe it would change gear irratically which it dosnt. possible duff map sensor?

Can anyone shed some light? Does this model have a idle speed controller?

Many thanks

The injector pump controls idle speed, there is a sequence to go through to get the idle stable again, have a read of this;

Thanks for your input.

Will this procedure be relevant for the 4m40 engine also?

I noted the document states 4m41

Thnks again

A funny thing is, before I repaired my pump 3.2 DiD it needed this done when I took the battery off. Now it doesn't. Which is a relief as my aircon needs fixed.

Could there be a problem inside the pump? Wear in the rotor head perhaps?

The Pump had a total refurb a couple of years ago along with injectors

I've noticed that my idle goes up and down from cold start. Seems to coincide with the glow plugs pulsing on and off. Actually almost stalls its self and will stall if driven at this point. I pressume from seal failure in the early stages but Im wondering if there could be another issue too?

I was going to try this but I dont have a belt to the A/C pump!

My Paj idles fine in N but when you engage D it'll drop's to a nice vehicle shaking <400 rpm!

ps i say "most cars.." because i dont know for sure that the pajero has such a device for killing the engine - first step would be to find out if it does?!

Would my Dads 4m40 fly by wire have an idle control motor?
