Skyline R32 Missing, Acceleration Cuts Out, And Stalling.

[LoveofCuteness]

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

Your Crank Angle Sensor is stuffed.

[LoveofCuteness]

Oh goody, you think that's pretty for sure? is this an expensive fix I'm looking at and will it be about to fully break down on me?

[Got a Pulsar]

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 !

My R32 stalled a few times over the past week. Never happened to my mate that owned it for 2 years! Will have a look into the CAS too.

[LoveofCuteness]

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

[Got a Pulsar]

If you can get access to a consult cable/software/laptop, it will talk to you.

[cree]

Will a diagnostic tester tell you if the cas was playing up?

[Got a Pulsar]

Haven't done it myself, but it should tell you fault codes referring to sensors etc, if there is a problem with them.

[LoveofCuteness]

where would you be able to get a consult cable and the software from? if possible

[starwarz]

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

[DVS JEZ]

Trippy man.

Send me a msg today if it is playing up still.

I'll order a LINK in

[cree]

I would say check AFM's first and see how it goes. Then check CAS sensor. Would the AFM's are easier to get to than the CAS?

[vh45tt]

afm is easy, cas is not so easy

[Hadouken]

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

[LoveofCuteness]

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...

Im pretty sure yours has become the infamous hunting idle rb's love so much.

I drove mine this morning, got it up to operating temp and it idled beautifully. Pretty confident that it is my filthy afm
