he he... I don't know.. I destroyed my motor and when I had it rebuilt the problem had gone... when we pulled the motor out we discovered the thermostat was dead so we replaced it... I believe it was the thermostat causing my problem but as you have replaced yours I don't think it would be that...???

sorry I can't be more help

cheers

Nick

id replace the coil packs or maybe jusrt borrow some i know what you said up the top but there is a first for everything and i had this problem once, i was driving along and bang it sounded like a rex, i thought it had dropped a cylinder or somthing, i got home took the cover off to see the coil packs tapped them a bit and bam up and running perfect and hasnt missed a beat since. although i still keep the alan key in the car just in case so it might be one of your coil packs isnt wright.

yeh thats a possiblity but its just harder wen checking when cold cause on the rb20det i can only reach cylinders 1-3 numbrs 4,5,6 are under the inlet piping :D

i dont use the cover on there but wen it breaks down wen hot u can just play around lookin 4 fault once engine is hot, but now being the cold issue i have limted time to fault find b4 it corrects itself and drives normal,

the fault is so annoying cause it is intermittant it wont do it many days, this will sound strange but it only happens on hot days once parkd out front work 4 9 hours then wne drive it goes rexxy till engine warms up. on a cooler day it wont do it!!!!

me confussed

:( :bs!: :bs!: :bs!:

Time to bite the bullet me thinks :)

Had this problem once for approx 2hrs....

changed spark plugs, put car back together :)......

sounds like a WRX!

take coil packs / plugs etc etc out again... tighten!

SKYLINE again!

in my opinion it was just a loose connection or something I hadn't tightened properly. Obviously yours is something more serious but everything points to the coil packs so if you can be bothered buy 1 and swap it round till you find the right one........ or if your made of money just replace em all :wassup:

okay wen my car is cold it goes in to sterioded rexxy mod until it gets warm mayb 5 mins driving , wen my coil pack go fualty they break down when hot so this leads me to beleive that it is not the coil packs!!!!!!

iam guessing spark plugs any suggestions any1

thanks ppls

Have you tried adjusting the tps? When it runs smoothly what idle rpm have you got. You have nothing to lose by adjusting the tps to lower the idle rpm if too high or vise versa to around 650/700 at idle. If tps is out of sinc it will give erratic readings and create hunting idle quality.

Well what i would do is, when up first start it and its missing or running on one less cylinder go through and unplug each coil 1 by 1 untill you find which one is the trouble one. You'll be able to tell which one it is because when you unplug the faulty one it will do nothing but sound the same but the others will make it sound worse, then simply replace it with a good one.

But if it is one of your coil packs, and you replace it, it wont be long and you'll have to replace them all I recon. So if you can aford it I would replace the lot with some splitfire ones(arond $650 if you shop about) or go for some seperate coils and run leads to your plugs eg: CDI type setup.

    • It's sodium citrate, I misspoke earlier. It's a citrate buffer solution. And yes, depending on how thin the metal in the tank is this may or may not be a wise decision but if it's just mild rust it should clean off and it should be fine. 
    • Price seems pretty good to me. Also seems a hell of a lot cheaper then buying another vehicle that only ever gets used for towing.  I'm a long way from you mate, I'm a couple of hours out of Brizzy. 
    • New [400]Z, they're available in manual and you don't have to worry about parts scarcity. 
    • Just planning to have the wiring neat and hide as much as possible.
    • The sodium acetate, mixed with citric acid, doesn't actually buffer each other. Interestingly though, if you used Sodium Acetate, and acetic acid, THAT becomes a buffer solution. Additionally, a weak acid that can attack a metal, is still a weak acid that can attack a metal. If you don't neutralise it, and wash it off, it's going to be able to keep attacking. It works the same way when battery acid dries, get that stuff somewhere, and then it gets wet, and off it goes again breaking things down. There's a reason why people prefer a weak acid, and it's because they want TIME to be able to be on their side. IE, DIY guys are happy to leave some mild steel in vinegar for 24 hours to get mill scale off. However, if you want to do it chemically in industry, you grab the muriatic acid. If you want to do it quicker at home, go for the acetic acid if you don't want muriatic around. At the end of the day, look at the above thumbnail, as it proves what I said in the earlier post, you can clean that fuel tank up all you want with the solution, but the rust that has now been removed was once the metal of the fuel tank. So how thin in spots is your fuel tank getting? If the magazine on the left, is the actual same magazine as on the right, you'll notice it even introduces more holes... Well, rust removal in general actually does that. The fuel tank isn't very thick. So, I'll state again, look to replace the tank, replace the fuel hanger, and pump, work out how the rust and shit is making it past the fuel filter, and getting into the injectors. That is the real problem. If the fuel filter were doing its job, the injectors wouldn't be blocked.
