Sick R33 Gts-t

[CleanGTS-t]

My Skyline's sick, just not running well

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...

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

what ecu are you using David?

[CleanGTS-t]

Stock ECU and Boost Controller.

Just the normal mods Pod Filter, Exhaust, Intercooler and BOV.

[vinnie32GTS4]

how much boost u running???

[CleanGTS-t]

Stock boost controller. So It'd be something like 6-8psi I think.

[shy_s6]

stock BOV? maybe its sticking?

if not unplugged battery n pump the brakes for 30seconds they hook it back up fire up n see how she runs

also take out AFM give it a good clean with contact cleaner ect

[CleanGTS-t]

I'll get some contact cleaner today and give it a squirt, see how it goes.

But whats up with the Taco?

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

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

[CleanGTS-t]

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.
