    Default Mitsubishi Pajero injector misfiring / workshop advice

    Good day,
    our Pajero gave us some problems recently, running loud and uneven after start, when I switch it off, it starts and runs normal.
    That happened a few times during our 12.000 km trip, but has stopped now.
    The engine also seems to have less power.
    We've been told I would need to repair or exchange the injectors.

    I did some googling and found four pages of workshops

    Could anyone give me an indication for a good reliable guy to do the job?

    From what I read, repairing and reusing the old injectors would be possible, new injectors would cost more.
    But we're an absolutely noobs when it comes to engines. Really need some pointers from your side.

    It's a 2009 LWB. 320.000 km

    Thanks so much.

    Hi,

    I'm going to send you a PM. Are you 100% sure its the injectors? If I recall, you had a run in with some dodgy diesel recently. This usually damages the SCV after a while (happened to me after a bad jerry can). Your symptoms sound very similar to a bad SCV. It's impossible to test injectors properly on the car.

    Cheers

    Hi Jean,

    Nope, not sure. Mitsubishi Polokwane could not read it out and wanted to send us to a "specialist" in Joburg.

    Thnx a million 😍

    Ah okay. Sounds about right.

    If you are in that area then you are in luck. The best Mitsu specialist in SA is in Alberton. Arnold Venter from Mitsi Tech Performance https://www.mitsitechperformance.co.za/ Miles better than any agent I've come across. A faulty SCV does not throw an error, but those who know the cars will identify it quickly (rough idle, low performance, surging under constant throttle, fluctuating rail pressure).

    Cheers

    start with the basics.

    Change the fuel filter again
    Change the SCV

    If the problem persists, only then have a look at the injectors.

    Ah okay you are back in the Western Cape. Well that's not an issue either. A few good mech's in the area.

    SCV = Suction Control Valve. It sits on the back on the fuel pump and regulates pressure to the common rail. It's a small part that takes about 15 min to change. It costs a few rands though (around R5k from Mitsu). But you can get the part cheaper from Toyota because the fuel delivery systems are both Denso. Common part to change on high mileage Mitsu engines.

    Cheers

    Good Afternoon

    If you are sure it is injectors, use Udel in Stellenbosch.

    Awesome. When they do the SCV make sure they fit the correct part and clean the area nicely before hand. Your Paj is the low power version so it has a different scv to the high power newer model. If you get the wrong part other issues wil manifest.

    Also when they fit it make sure they initialize it and do a small quantity injector relearn using the correct computer tool. If not it may (or may not) act up.

    Let us know ��

    Agreed, most I speak to also recommend them.
