noticed some black/grey smoke come from my exhaust today under heavy acceleration from first to second.

what could this problem be. anything i can check before sending it to the mechanic?

and if so, is it an easy enough job to fix myself or with a mate.

cheers.

I suggest you switch your car from camels to a mild brand, preferably with menthol

previous owner told me it is running rich, which i have noticed aswel. cheers for the help, just worrying as first turbo ive had

best serious advice i can give, is to take it to a qualified tuner to check your o2 sensors, the afm ratios reported by an external sensor, and then give the car a good tune up...

i know of many places north of the city that can help you

who do you reccomend dohmar?

road and track dyno services in 19 Thomas St, Cavan (8344 8930)

They have extensive experience with all types of motorsport, and I personally dont trust anyone except these guys...

while boostworx is around the corner, i'll still be going to these blokes, no disrespect to bw tho (ive never been a customer)

it's just running rich like chad said, you can take it to some one to check your AFR's (Not AFMR's)but there is nothing they can do about it anyway because you can't tune anything with the standard ECU, all they can do is play with your timing.

Just take it to anyplace that has a dyno and get them to run it up to check the AFR's get the print out and post it up here and we'll go from there.

Shop around because you shouldn't be paying more than $80 for a few quick runs, otherwise wait till someone is holding a dyno day and do it then.

I only use & recommend Boostworx

new years they are moving to cavan from pasadena

Awesome! Closer to me. :)

I'd been a customer of theirs since back in the day Craig ran Mad Dat from there ... when I sold my house down south and moved to the Regency area, it was just too far to travel to get there. Thats good news ... for me anyway :)

burning black is too rich, the grey is more water in tailpipe MOST of the time.

if you car is cold when you boot it the mixture will be really black, grey

your O2 sensor is prob dirty, and the intake plenum is prob caked with carbon as well.

spark plugs, otherwise it sounds normal for a turbo car.

    • Yeah since those first 2 replies I actually went and put some 98 in it and tbf it's already doing much better than the 95 (which is weird and makes my inner tinfoil hat wearer think the 95 was a crap batch), getting 8ish around town. Again, wonder if it takes a while to stabilize if the fuel is changed a couple of times. I swear cars used to just either run "well" or "s**t* in my 20s, none of this fuel optimisation business haha 
    • Any number of different ways. Have the coils draw sufficient current to provide contact wetting. Use different contacts in the switch, either by material or design, better suited to the low current drawn by a relay coil. Etc.
    • Hmm, how does the R34 manage to have headlight relays then without getting excessive carbon buildup on the headlight switch contacts?
    • Not R7R. Meant to type R&R, obviously enough.
    • Bugger "making it look stock". I put one conventional internally fused Hella relay behind each globe. I just pulled the plugs off the back of the globes and built new loom segments with male and female plug parts to match up to the original loom and the globe, and used the original power wires to each globe coming from the switch through the original loom plug to trigger the relays. Ran a big fat (also separately fused) power wire across the front of the car to feed all the relays. It's as ugly as f**k, but it is wedged down between the headlight and battery on the RHS and the airbox and headlight on the LHS, and no-one ever looks in my engine bay, and on the odd occasion that they do I simply give no f**ks for what they think. Fully reversible - not that you'd ever want to. For f**k's sake. It's a Skyline. They made million of the bloody things. We've been crashing them into roadside furniture for 30 years now. There is a negative side effect to putting relays on the headlights. The coil current is too little to properly clean the contacts in the switches and they get blacked up and you have to open them up every couple of years and clean them manually. I have 25 years of experience on this point.
