Hey,

I've searched the forum looking and hopping to find a cure for what ever is wrong with my car, I've done some things people have listed and so far nothing... This is my pickle...

I pas going to put this down as bad fuel but I've had about a tank and half since then from another BP...

When I'm driving, foot on the peddle just coasting along, and all of a sudden-out-of-the-blue, rev's drop (a lot) , no power, and a little bit of a cough, splutter and a small fit. If I try to plant it it just makes it worse and it keeps on coughing. If I put the clutch in the rev's drop that much it almost stalls. If I put the clutch in and give it a small kick on the go-fast-foot-rest, he's all good.

Ever since this started happening which was about a week ago it feels like it doesn't have the same pull. (I don't know if I've gotten used to the boost or what...)

I've just changed the fuel filter and that was a bitch... I've added a small bit of injector cleaner too and the problem is still there. But I will admit the pulling sensation does seem a bit better.

So here's the question.... Any I dears ?

The more I dears the better,

Thanks in advance

Justin.

OK, I don't know what you mean when you are refering to a " cas " if your trying to say my car has shot its self, then yeah... As for the tacho needle, yeah it drops.

On my way to get some plugs it happened all over again. I just finished changing the plugs and took it for a boot. When I was giving it stick there was a heap load of miss firing going on. And as I was changing the plugs I noticed the air pods are all dirty, like black, dirty. Turns out for some reason oil is coming out from one of air pods...

Not healthy, I know...

I'm not to sure if its all the blow by / blow back gas or maybe one of my turbos have gone kapoot... My old man said something about the PCV Valve might be shot and causing the oil business...

Just what I always wanted... A whole new kettle of stupid fish.

Anymore I dears?

Had the same symptoms on my 33 gts-t, was the cas.. I took it apart afterwards and it turned out that a piece of metal had shimmed off inside and was randomly blocking the led inside of it.

Another thing to check that causes similar symptoms would be your air flow meters. Over time the solder joints on the inside of it go brittle and snap, causing random voltage fluctuations inside the ecu causing you to run rich and misfire under load.

If you're blowing dirty amounts of black smoke (fuel) then I'd be looking at the afm's, if it's just a little random black smoke then I'd say the cas (Retarded ignition as opposed to no ignition at all :P

Wouldn't be overly worried about the oil coming out of one of your pods, I'd say it's actually venting somewhere, perhaps as your father said the PCV valve then getting sucked back in through the pods, causing it to build up on the outside of the filter. Sit down one weekend with about 10 cans of that nice $2 degreaser you get and clean out the engine bay, as it'll have shitloads of dirt & grime built up, and once it's clean you'll be able to spot oil leaks alot easier :)

OK... Check this shit out.

The other weekend I took off the air filters and the air mass meters to give them a clean. WhileI was doing it I noticed in the front turbo pipping a nice little puddle of oil right in front of the turbo housing. I cleaned up as much as I could and cleaned the air mass meters with loads of break cleaner, threw them back in a and went for a spin. It all seemed good untill after a 10 mins or so and the same problem came back.

My thought is... Because all the oil is (possible) leaking out the turbo, going through the cooler and to the plennum / bov's and when it creats boost and back off the bov's let it out (but not all the bost), and so come of the pressure is kept inside the plumbing forcing back and blowing / spraying the air mass meeters with oil and and giving it a faulty reading and there fore giving me the shits. (ya dig?)

I left my car with a mechanic mate of mine for the week and let them play arround with it. They told me exactually what I told them... I appriceate it, but they are like titts on a bull...

      R33 Fuel Pump & Brakes after alarm swap

      Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?

      Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.

      After market rear camber arm adjustment

      By GTSBoy · Posted

      Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.

      R33 Fuel Pump & Brakes after alarm swap

      Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
