thanks guys. but a question though, the problem with the car is spermatic, is intermittent so wouldnt this make it near impossible to spot? so no option, pull the plenum and check the injectors? so get them flow tested etc? then i guess if that turns up 0 answers, fuel leak.
Not much else you can do. Black smoke says way too much fuel and only way you can get too much fuel is leaky injector, or stuffed o-rings. Ohm the injectors, if good get them cleaned and new o-rings. If don't ohm good get new ones.
Grey as in a tinge of blue? Or white? White is coolant, blue is oil, black is fuel. Do a compression test. Any sludge or oil in your coolant?
OK, a little lesson on smoke and what causes it. Blue smoke, oil, vale stem seals, piston rings or turbos White smoke, coolant, head gaskets, cracked heads or block. Dissipates very quickly like steam. Black smoke, excess fuel, atomized fuel will show black smoke from the carbonization due to incomplete combustion, injectors, injector o'rings, timing or fuel maps, damper or reg faulty. White/grey smoke, excess fuel, unatomized fuel, completely unburnt fuel from way too much fuel in the cylinder wetting out the plug and not firing at all, injectors, o'rings, damper, reg. This is not a definitive list of what causes the problem, but is the most common causes. 'Usually if an injector o'ring is gone, it will result in hard starting, possible misfiring, rough running, excess fuel smell. This is not an intermittent fault. I would be looking at the injectors themselves after having checked the reg and damper are not leaking into the plenum.
evan, if i want english lessons mate, i'll be in contact. until then, stay out of my thread ok? you useless spamming of a TECHNICAL thread with spelling mistake's is hardly the worst of my troubles. Down right annoying and pretty f@@ken stupid. i dont understand why, when trolls get in ZRT and cry over a mis-spelt word. not only does no one care, you come across as a no-nothing toss. i would love to list everything that makes me LOL @ you but i sense someone would cry wolf. so if you have a problem PM me. if not... piss off, is about the nicest way i can put it, unless you have nothing better to do than nit pick more mistakes from this. :F: :F:
this is me. its a grey/white smoke. and as i showed 'cleary' tonight, its spitting unburnt fuel out the exhaust. its like pouring out, but only from the right exhaust as andrew noted. yeah i have hard starting. it sometimes wont crank, then after a few times coughs and splutters to a start or full throttle on and it will. as andrew noted it runs really rough and the fuel smell is there. both engine bay and in the smoke coming from the rear. however mine at the moment is intermittent, honestly what would be your suggestion on the likely cause? it only seems to lose a cylinder whilst driving, on idle it occasionally does this. the smoking / rough idle etc. ok so check the fuel regulator and damper ? so pull the plenum and look at where? should get a tech guide on this happening.. and if that fails, get the injectors cleaned and flow tested. thanks heaps guys. will have the plenum off this weekend and more work started
rod all that is wrong with your car is the TPS... just fix it and it should be sweet:bash::bash: (spelling????) Andrew
signs of head gasket leakage only really show when the engine is cold e.g hard starting and blowing pure white smoke and normally clear up once warm. i know youve sed that your car does this but unless the leak is really bad it shouldnt blow smoke like that when warm which you also sed it has done before. but this wouldnt have anything to do with the fuel smell... i'm a little stumped atm at least untill i can bring some tools and have a proper look over the car. i've got a cooling system pressure tester and a carbon monoxide tester which should show if the head gasket is leaking or not Andrew
should i check my guard liners to? thought they may be causing it. you free this weekend mate to give me a hand?
Rod's is a manual, so that rules out auto gearbox operation. Leaving the TPS alone and looking at fuel related components, could a shitty fuel pressure reg cause this type of thing? Rodsta sorry if I missed it, but are you getting any codes? (if you haven't got ready access to a conzult, you can manually twist a small knob on the ECU to get codes, tech section has article), worst comes to worst, we'll have another tech day -Kirill
ey kirillster me and dad thought the same, seems like the fuel pressure reg was playing up causing her to run epically rich. but the unburnt fuel and me loosing a cylinder + the mass amounts of smoke stump us. and i dont have access to it yet, will try to get hold of adam but i doubt he is free for a long time, so will tech guide it! maybe if your free this weekend we can have a smash the shit out of this piece of shit day. better suits me, lol. nah going to get the plenum off, but the more hands the better...? kindest regards. rod.
Should be good to come, pm me details of when. Btw, if we're taking plenum off, don't order a plenum gasket, i've got a spare you can have. -Kirill
ok will do brother! ahhh thanks kirill yeah pretty sure the plenum is coming off maybe new injectors going in. will PM ya.
Hey guys my car is running like shit, my tps is out but im not gonna correct that before posting here asking for help. :bash: As said it is and was the 1st step. Its highly amusing how Rod, and yourself take other peoples sentences out of context and and manipulate them to spew out more bullshit. :rofl: Last time I said, "Twin turbos don't have much lag" the reply was "Are you seriously saying they have faster spool up times than a supercharger?" :rofl: I love it guys keep up the lol's.
lol your such a fool. when did i manipulate your sentences? and re-read your post. you clearly were hinting that turbos spooled quicker. you just need to forget the past. and as for your TPS comment. i'll repay the favour as per your latest thread. 'erratic vacuum with air con on" you could fix the erratic vacuum by turning the air con off. ROFL. thanks anyways for making me laugh. and helping?
HAHAHA yea I hinted it when I didnt even use the word "supercharger" in my post. Thank you so much for taking what I said and then telling me what I meant :rofl: I corrected your "3000rpm stock 300zx turbo spool up time" tho. In fact here I'll quote you exactly. "lol we all have dreams mate in no time you mean 3.5k?". HAHAHA maybe some new ignition coils would fix your problem? The erratic vacuum cured by turning the aircon off? my god why didnt I think of that, your amazing. I'll just keep the aircon off forever to hide the problem. What it comes down to is, you coming here asking for help saying your TPS is set incorrectly and then rejecting anyone who suggests correcting it. :rofl:
