Hi guys just a quick one I'm fixing my Mates 32 Gtr that when he was driving it started losing power then stalled. Dis connected afm s and it ran but badly as expected just enough to get it on trailer. While running if I re connect either of the z32 it stalls and when started again won't rev under load or above 2.5k stationary. It has fuel pressure at the rail and the pump and I pressure tested inlet track with no leaks found or heard. Is there a way to test afms? Would it be possible that both fail? They are genuine Bosch units and were brand new and have done dyno and drag strip work only Max 5000ks. I was thinking maybe a mouse chewed a wire as the car sits for long periods but cant see any also this happened after re fueling. It's running nistune ecu and we have battery also dis connected for long periods is it possible for settings to change once the nistune has been set up? As in revert to stock afm setting?

Scott

      Unpeeling the Orange

      I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!

      Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.

      The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!

      The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
