Skyline r32 20det missing and stalling, will be driving and acceleration cuts out for a few seconds then put foot back down and comes back, or like today for the first time won't come back and stalls, or stalls randomly at lights and has trouble starting again sometimes, has run great for 8 months, just started this a few days ago, seems like it's doing it more and don't like driving knowing I could break down at traffic lights if it decides to stall and not want to restart ...

AFM connection, coils, fuel pump or something? anyone had this prob? needa sort it asap

Does it only happen when car is warmed up?

Sounds alot like when my old Bluebirds CAS was on it's last legs.

Cutting out at approx the same place daily on the way to work, ignition cutting out and kicking back in, stalling and not wanting to start for a couple of minutes etc.

New CAS, no problems.

Could also be AFM related but I'm leaning towards CAS.

Search for "Crank Angle Sensor" & see what comes up.

I think it is only when it's warm, I'll see in the morning as I need to get to uni, not looking forward to driving it at all was hoping it would at least be OK through till friday but it seems alot worse... may have to try hunt down a cas tomorrow, or find out if some one can confirm the problem.. thanks so much for the help at least now I have a likely cause for this... its very annoying!

Freaks you out when your'e hummin' along and suddenly everything stops.

Popping the bonnet at the lights isn't much fun either.

Goodluck, hope you get it sorted soon.

Oh and Welcome to SAU !

Yea never had any problems up till now, have searched up symptons and there's been too many causes to figure it out.. like air flow meter connection, coils, cas good to get some peoples opinions here as well to match whats happening, wish my car could talk and just tell me wassup

ECUtalk cable, its the most practical imo, comes with a USB connection and software !.

Dont go the chinese route and get a RS232 those things are so oldschool you need a laptop with a RS232 port,

if you dont then you need to get a USB-RS232 converter and thats just annoying you will end up

spending $$ to get it to work. ECUtalk best bet its like $80 and in with the times.

Its a poor mans Multi Functional Display.

Thought Id bring this thread back.

Tonight something weird happened. I was driving (just entered sydney from the central coast), slowed down for a round about, and got through it, then on the other side I applied about 5% throttle just to coast along, and it hung on to 2,000 rpm for at least 2/3 seconds I was then about to get off the throttle, and then it started to gain revs again.

Then I pull into the garage, park, I then jump out to have a sticky beak at any noises, and I can hear the car slightly dropping and picking up revs, power fc said about 200/300 rpm. And then it stalled, so I crank her up, she starts first go, and I let her idle, same thing again, stall after about 10 sec.

Hmmmmm... Im thinking my AFM is farked, or TPS. Am I on the right track? Im going to check tomorrow to see if its still doing it, if it is still misbehaving then Ill unplug the AFM's and see if it persists.

Or am I just chasing my tail and I should be looking at the CAS?

BTW, if my AFM's are f**ked then, Jez mah man, get that LINK ready

Its all apart atm. Cas is looking good still. Gears still have good teeth.

Afm, one has some oil on the element. Will be cleaning them and putting cstch can in to prevent this in the future.

If this doesnt fix it, then I am done with afms haha

Mine is still doing it, have taken it into get fixed and they did an oxygen sensor somewhere under manifold and the spark plugs which they thought fixed it but turns out once I got it back wasnt fixed so she's going back in.

@Hadouken Mine has started doing something similar to yours over the last 2 weeks which it wasn't initially doing once the missing started, when it's idling she can't keep the rev's stable, stays stable a little bit, rises, falls, rises, falls, and usually will end up stalling, sometimes quickly sometimes takes a bit. As you can imagine this is annoying as hell at traffic lights...

Oh well, gotta get through this week with her in this condition in the city while I'm at uni and take her back home to get back into the workshop and use a family vehicle while it gets fixed...

    • I'd argue the F50 kit I got is very good value. For ~2k I got the calipers (refurbed condition), adapters, pads, brake lines, rotors, and top hats. I think you'd be pretty hard to get Evo/GTR/350z brembos + the additional hardware for similar money. Used market for a pair of front calipers alone I've seen tend to run anywhere from $1500-2000 depending on condition.    That said, something like a GTR or 350z brembo is a lot easier to adapt to the Silvia. 
    • Is there a significant price difference between the Evo/gtr/350z brembos vs the F50? Looks amazing.
    • I was actually being a tightarse at the time LOL... My OCD is tickling me into running a 2nd 8AN Teflon hose all the way down and removing the 2x OEM hardlines. My other side of my brain is telling me to run 2x hardlines front to back (also acts as a fuel cooler, so win win).
    • As I mentioned in an earlier post, I had some trouble with the Silvia's brakes dragging back in 2023. I managed to sort it out then, but the same problem came back to bite me late last year. Just take a look at the picture – I had a feeling the handbrake was acting up again, and I was right. Anyway, I'd been wanting to upgrade to bigger brakes for a while. Not that the Silvia's brakes were bad, but it was more of a "want" than a "need", you know? It was funny, though – at the time, I couldn't find any Evo Brembos, 350Z Brembos, or GTR Brembos for a decent price (of course, tons of them popped up online after I already bought my kit!). I ended up going with an F50 Brembo kit, which came with adapters, brake lines, 330mm rotors, and top hats. The F50 Brembo caliper was used in a few other cars too, like the FPV. I also decided this was the perfect opportunity to ditch the Silvia's ridiculous rear brakes and that awful handbrake (some of you were definitely right about that!). I picked up some R33 calipers and all the necessary bits – rear drums, backing plates, and new hardware to refurbish the calipers. Of course, it wouldn't be a project without a few hiccups. Turns out the brake master cylinder was playing up and basically (to put it simply) keeping the brakes engaged. I had it overhauled, and after some adjustments, everything was working again. The whole process took a while, as you can imagine. To top it off, the front right wheel bearings were shot and needed replacing too. This is a rare occasion where I'm posting an update while it's all still fresh! These pictures were taken just this afternoon.
    • I was just going to say that it's good to see you picking up the pace again. Hope the surgery goes well. More downtime just means more time to come up with new ways of digging a deeper rabbithole
