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.

      It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪

      And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil

      Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.
