My Skyline's sick, just not running well :D

At idle there's black smoke coming out of the exhaust (unburnt fuel) and if I boot it, still black smoke.

So running rich I'd say...

Now some sometimes when I pull up and she drops down to idle, it'll die off and come back up repeatedly. A bit like it would if an inter cooler pipe has come off (but there all OK).

This is not all of the time. All of the above is temperamental. One minute all seems well, normal. And the next minute not so good.

So, I'm thinking that I may be up for a new Airflow meter or O2 Sensor.

Something to note: It has been like this not long after a Service and Tune at 'Un-named firm' about 1 month ago.

Something else to note: I have installed a Air/Fuel mixture gauge, this involve wiring to the O2 Sensor. I installed this before my previous service and tune

where there was no problems. So I don't think this is the problem unless maybe, there's a voltage issue of some sort. Long term load/drag thingy... I dunno... :cool:

And here's what is really freaking me out. My Taco has freaky moments just as temperamental as the above and started the same time. It'll be fine doing its job, next

minute it'll be flickering all over the place. Then go back to normal :)

It's different from day to day. What has happened?

Anyone got any idea what may be going on inside my Skyline?

Or know of some things that could cause these problems?

I've got it booked in to be looked at next week. Have to get it sorted so I can stop worrying and enjoy her again.

Thanks ppl

Does the smoke have a smell to it?? (fuel/oil smell)

I had the exact same problem my issue ended up being the AFM

Yeah I'm leaning towards AFM. Because it's running rich on and off. I'm starting to think. If the AFM is starting to sense in-correctly it may have an affect on the Taco too

causing it to do it's flickering thing.

Does the smoke have a smell to it?? (fuel/oil smell)

Big sniff... cough, cough, cough... Fuel :)

Have given the AFM a bit of a clean, has been running fine today. I wont know if that'll do it 'till it has a hissy again.

Been ringing around for prices today. AFM with (Pink) Sticker I've been quoted between $150 - $295. Bit of variation out there.

Have you also tried re soldering the afm?? its only a temp fix really but its a def worth a try.

This worked. The terminals were broken off. Well are now...

I ended up taking out the four screws for the plug and pulling that out, witch I think broke off the last connected terminal. There was little resistance to take it off.

This is how NOT to do it I think LOL

Not sure how you get in there to solder them back on?? Do ya cut or pry the side plate off?

I ended up bending the terminals over a little so when i reinstalled the plug panel bit, they pressed firmly against the pins. Bit dodgy but has got me outta trouble and she running nice. Gave the sensor a clean too. Everything seems back to normal and smooth running.

I'm keen to solder them back on though. So a quick 'how to' To get the side panel off the AFM would be cool.

Thank guys.

    • I like it when the counter chick leads you out the back into the racks and says "have a grub around in here and see if you can find what you need. I'll be back in a few minutes. Just left me in front of a massive motorised shelving system and 2-3 million fasteners, so I could find a peculiar SS shoulder bolt with cap head. Gotta love country towns.
    • I used this https://osgiken.com.au/product/os-giken-os-250r-lsd-gear-oil-80w250-1-litre/   shut my nismo 1.5 pro up by heaps…. Not silent though. Gives the car character and personality. It ain’t a carolla. If you want silent, put a quaife in it.
    • It's about the same time for me from Bunnings, or the Fasteners. My big push away from takeaway food, and gluten in general keeps me away from the Bunnings Snags too! Weather up here, I've been out for two walks today in the beautiful sunshine. Had a few little drizzles, and some wind, that honestly, a tin of beans and I could compete on how harsh she blows Thankfully, being this bit inland, we're not getting anything much really. Will probably pick up a bit more when/if Cyclone Alfie decides to come ashore. A few areas in the GC though, and south into NSW are really getting smashed though! Right now, I'm just annoyed Alfie hasn't hit, as I'm not allowed to crack into the BBQ foods like the bacon and eggs until the Cyclone hits "In case we lose power"...
    • I love fastener joints, the price difference between them and joints like Bunnings or Super Cheap is amazing, and they either have exactly what you want, or they can get it to quick They have even given me some for free when I only needed a couple of specific size In saying this, I have paid premium for fasteners from Bunnings if they have the sizes I need, but only for convenience really, as my local is only 10 minutes away, the Sushi joint near them is also a consideration  How's the weather Matt? Stay safe mate
    • Wideband is worth setting up if only for tuning purposes. I would not mess with the ignition system unless there's a misfire. HKS crank trigger is popular out here for the relatively easily sourced Denso crank sensor, not a bad idea to install as well regardless of power level on a standalone. Boost leak test is worth thinking about. Oil pressure sensor tied to a fuel cut isn't a bad idea either. Getting the tune figured out is a good idea. Without putting eyes on it and getting under it there's no way for us to tell you exactly what it needs but most likely you're down to the last 10% that will make a big, big difference in how happy you are with the car.
