R32 Afm Problem, Running Really Rough.

Hey all

So basically i am new to the forum as I am new to skylines. I have recently bought a r32 skyline and need help as it has an afm problem due to one of the wires that goes into the plug has been snapped off just after the plug.

I took the plug off by cutting the plug and they got my dad to fix the plug for me. no dramas. One i had the plug fixed and ready to operate I just connected the wires dodgy to get it working to make sure everything was ok.

I reset the ecu by disconnecting the battery and then holding down the brake.

Once i reset the ecu I started the car and it would not idle. I had to hold the throttle fully open to JUST get it to idle and then once I let go of the throttle it stalls. I then disconnected the afm and start the car and it idled at about 1250 rpm. It idled rough but still better then when the AFM was connected.

Does anyone have any idea what the problem is? Anyone ever had this problem before?

Any help would be greatly appreciated. cheers Tyrone

Got a new AFM and it seems a little better but still has the same problem.

Did another ECU scan came up will fault code 12, which is the MAF sensor circuit. Could it be the wires connecting the plug to the afm as all for wires are only twisted together.

Also the engine will keep stalling and it won't rev past 4000 rpm.

Any suggestions? Any help will be really helpful.

      Had another look at the car and I noticed the fuel pump isn't priming on ignition. I'd taken out the pump from the boot to siphon out the old fuel, so maybe I've knocked something loose or broken a wire putting things back together. Will go back with a multimeter and try to work out what's stuffed. Kinda hoping it's the pump itself thats gone so I can upgrade it

      Yeah agreed, you can't assume that shop are they only people who ever had to work on it. It was just a guess on the mods based on how things were done back then. You can check the Air Flow Meters by the part number on their tags, they are likely either Z32 or Nismo ones (both read about the same but the Z32 one is a little larger while nismo is stock size but supports the higher airflow like a Z32). And yes, all that would get you to 450hp / 340kw To tell what is happening with the turbos, you want a photo of the tag on the core, that will say what it was made out of  (they can retain the front and rear covers to make the plumbing easier)

      1992 R32 GT-R Race Car

      By bardabe · Posted

      I'm selling my personal race car. 1992 BNR32 Skyline GT-R About eight years ago the engine developed the dreaded low oil pressure problem. I removed it and found the issue. However shortly after I moved half way across the country, moved my work shop, bought a house, got married, then moved my shop again to it's permanent location for the time being. in turn I do not have the time to race this car as it should be. In turn the engine I built for this car will end up in my street car and this car I hope finds a home with someone who can use it to it's full potential. The roll bar was built by Jason Noren Fabricaiton in Pomona California to SCCA and NASA Specs. The car used to compete in redline time attack and global time attack enthusiast class. It also has a fire suppression system.  The car is with me at my workshop in Kyle Texas, USA. Shipping it is no problem, I can personally deliver the car to the port of either Houston or Los Angeles. Any other port depending on where it is may require transport but we can always work that out.   The chassis itself is rust free, rear quarters and under fenders are free of any rust so it's a very solid foundation for anyone who wishes to move forward with it. As posted and at the asking price of $20,000 USD the car includes all of the following;   All OEM Body panels, front fenders, rear bumpers etc.  OEM Nissan Projector headlamps (Pictured N1 lamps were removed) OEM Nismo Side Skirts / Extensions OEM Rear Spats  Front & Rear Subframes are installed car is full roller Rear Subframe has Cusco Camber Arms, Whiteline HICAS Elimination Front Subframe has Whiteline tension rods and whiteline Sway bars w/ endlinks.  Buddy Club N1 Coilovers All chassis wiring and engine wiring is in tact. Attessa System is fully in tact and was functional before engine removal.  BCNR33 GT-R Brembo Brakes F+R with Endless MX72 Plus Pads, DBA Rotors & Stainless Steel Brake lines Billion Racing Radiator Billion Radiator Hoses Fluidyne Engine Oil Cooler Accusump System (trunk Mounted) 5 Speed Transmission w/ Transfer Case F+R Prop-shafts Rear Differential With rear Axles.  Nismo Gauge Cluster Nismo Clutch + Flywheel   Essentially what is needed to make this car running and driving again is as follows: A working Engine, an ECU, and time to put it together. The price posted is or best offer as I am willing to remove some components to accommodate price to a certain extent. If any serious buyer wants full detailed pictures, videos, or any questions I'll be happy to answer them. I believe this car is priced to move quickly considering it's a rust free and very straight chassis but always open to fair negotiation.  I can be contacted via phone or email.
