    GQ diesels had mechanical injector pumps so no MAF sensor.

    Great thanks Tony.

    I'm not going mad and since I've just found out this plus the fact I already have a EGR shim I'm off to the mech to get the injectors done to hopefully stop the cloud of black smoke...

    Cheers, Lachie

    Hey mate, I had the same problem with it going into limp mode under load, lift off the accelerator then power on again and it comes good for a while. For me it seemed no matter what rev's I was at, if it stayed over 11psi for more then say 10 seconds it went into limp mode.

    Replaced the maf with a genuine nissan sensor and no more overboosting limp mode.

    I've also blocked my egr, and put a dawes and needle valve on.

    I just wanted to say that having done the maf sensor a couple of times using that spray, as demonstrated on this thread , i'm pleased to say that having done some day trips around the outskirts of Melb. recently and pushing the GU3 3lt td through the hills pretty hard , it did not let me down 1 bit , no loss of power at all , just spot on , actually put a smile on my face . now i have some confidence to go bush, DEEEEP bush .......!!!!

    Unless you're trying to clear error logs from the ECU - I left mine overnight to be sure when I had the coolant temp sensor problem, but I believe the manual states it can take up to 24 hours for a manual reset (battery disconnect) to clear all errors.
