We have had a bucket load of rain up here in FNQ and I had to drive through some fairly deep water.

After this under boost i think i sucked some water in as the car pulled back quite sharply and then went forwards again, like a big stutter.

Since then the car has started hunting very badly on the way to work, and when cold revs very high - over 2300 rpm.

Does this mean my AFM is probably buggered? I cant see any obvious vacuum leaks.

Idle control valve was cleaned fairly recently too, so i dont think its that.

Problem seems to get a lot better once car is warm.

Is there anyway to fix a z32 AFM, this one is quite new and I dont want to buy another one already.

Thanks

I guess its always a possiblity but you would think it would take some serious rain for it to get sucked into the intake. Best bet would be to go to your local Nissan workshop and get them to do a diagnostics check. Errors will show up for AFM if it is buggered.

Haha serious rain... have you seen the news lately? Areas up here have been getting 400-700mm in a 24hr period. It has been absolutely pouring.

I will check powerFC voltages... I forgot I could do that.

Cheers

      R32 only blows hot air

      By Duncan · Posted

      Not really, but the heater box is pretty simple mechanically....if the door is one way the air bypasses the heater core and if it is the other way it goes through it for warm air.  If you are sure the actuator you moved manually is for the heater mix (there would also be one for output air direction) then I'd take the heater box out and see what is happening (you'll have to regass and re-coolant the systems afterwards) BTW pp724 onwards from the GTR workshop manual cover the system in good detail, it is probably worth checking. I think the IAT sensor might be a problem electrically for getting cold (if you got 24 error code not -24 it thinks the incoming air is -50c) and it covers how to test the sensor (although most likely it is either not plugged in or a wire is damaged)

      Leaking Rear Subframe Bushing?

      Use the GKTech subframe bush and bring your subframe 10mm closer to the chassis. You'll need to fix an exhaust hanger to suit. One of the best mods I've done.

      Wires cut underneath shifter cover

      You'd really have to pull it apart further to know, it least you can be confident that the one heading to the back is not connected any more. There was once a ground on the shifter seal mount too, your head unit issue could be that simple

      Perfect, I'll get to it this winter then at the same time as I weld on my anti squat kit.

      R32 only blows hot air

      By SeanR32GtSt · Posted

      Alright so my 32 only has one temperature no matter what degree you set it to. I’ve tried disconnecting the servo motor arm and moving it either direction and got no change. I’ve fixed the leak in my AC and re charged it and with it on and clutch engaged it still blows hot even though the low pressure pipe going to the firewall is ice cold. Both heater core hoses are hot while running as well. Diagnostic code showed 24 for intake air temperature sensor. Anybody got any ideas?
