    Default GWM idling problem

    I drive a GWM Sailor 2.2mpi with the 4Y engine. Sometimes when I start the bakkie the revs go above 2000 when idling. If I switch it off and wait a few minutes, then start it again, it's fine +-1100. I have cleaned the IAC valve(which was very dirty) but it still does it. Now more often than before.
    Most of the time when I'm driving 120km/h the revs sit on 4200, which is very high in my opinion. Only a few times on the open road did it sit on 3000 revs which I think is about normal. Also going through the gears the revs are very high. Sometimes it idles a bit rough which it never did before.
    Any advice?

    The idle regulator would have been my first call, but not at 2000 rpm.

    Is it not the accelerator cable that is sticky? If it idles so high, have you tried to close the throttle body with your finger?

    Sometimes I start it and it would idle fine, then after about 5 seconds the idling would all of a sudden go to over 2000 revs

    Only way that can happen is if the tb opens. The 2.2 is not drive by wire.

    THe MAP sensor on top of the intake manifold is getting oil vapour from the valve cover breather. remove and spray clean with a good electrical contact cleaner or maf cleaner. On my bakkie this was the cause of irregular idling.

    The rev change at highway speeds can only be two things
    1) the clutch is slipping or

    2) the rev counter is going nuts

    Soos ek se dit was die workhorse wat ek gaan ry het. Die 2.4 het so 3500 by 120 geloop, en my 2.5 het naby aan 3000 gekom, kan ook nie so mooi onthou nie....

    Ja dit is 'n Chinese revcounter maar ek kan hoor die revs gaan op.
    I think I found the idling problem. There is some electrical device on the throttle body underneath the IAC which is either the choke or the MAP sensor as was mentioned by FLOOI. It was idling high and I disconnected the cable to it, the idling came down to just above 1000 revs. The engine management light came on then, but I reset it by taking the ECU fuses out for a few seconds.
    If that is the MAP sensor, then I can just clean it. For the highway revs, maybe Pierre is right, but it is very high to me. It only gives you 500rpm spare before it hits the red on 5000, when driving 120km\h

    I had a look on Google and it is the TPS sensor that I disconnected which brought the idling down.

    Ek sal nie worry oor die redline nie... dis baie konservatief vir n petrol.

    Maar hulle moet die engine so hoog laat ref, anders is daar net nie genoeg krag nie...

    I do believe mixing electricity and water is how you accelerate death.

    I sprayed the TPS with switch cleaner and all was well for about 3 days. Even my revs was at a normal amount when driving on the highway. But it is doing it again now. So I will by a new TPS. Can't get one at any Spare shop and GWM wants to charge me R4000 for one. (The most expensive variable resistor I ever came accross).
    So I will import one from the UK for about R236.
