Went to gippsland yesterday from frankston, didnt miss a beat for the whole 340k's, even got 10.5ltrs/100k's, this morning i started it and it run fine, decided to work on it instaed of going to spend money so i turned it off, been having problems since i installed my lcd nismo cluster, it says im doing half the speed im actually doing so i thought i would put the old one back in and see if that fixed it, before i put the facia back on i took it for a quick spin, as soon as i started it i relised something was wrong, it idled like a pig and every time you reved it there was a cloud of black smoke, took it for a quick spin after stalling 3 times trying to get it out of the drive way, stalled a couple of more times whilst slowing for speed humps and still putting out black smoke.

Question is what is behind the cluster that could cause this to happen?

Took out the plugs and attached pics, they look bad but im assuming it is more from un burnt fuel.

How do i check my coils and ignitor to make sure they are working properly?

This is a video of it idling.

yep swapped them back and it still has the same problem, i then removed it all together and still the same problem, cleaned everything up (couldnt get new spark plugs today so i just put the old ones back in) and put it back together, run about 90% good untill i touched the accelerator then it went back to shit, will get new plugs tomorrow and see if its just that, im assuming its possibly igniter and/or coil packs but would like some more info on testing before i replace them.

Worked out how to do it, code comes up as 2 long flashes and one short one which i believe is 21?

Now i just have to figure out what it means, all the threads i find does not have a definate cause of a 21 fault code, seems to be a cas, igniter or coil pack problem, any one know which one is the best to start with?

Just replaced the cas it it would not start at all, sounds like its trying to kick on a couple of cylinders but just wont turn start, put the old one back on that the engine would start with but run like shyte and now it wont start with that one either.

Any one have any ideas, gotta be someone out there with an idea??

  • 2 weeks later...

I have since gotten the car to start, i have replaced the afm, coil paks and ecu with no change, still trying to get a hold of an igniter.

Any suggestions would be appreciated.

Does anyone know how to read fault codes, when i first did it the fault code came up as 2 long flash's and one short one, i assumed this meant 21, after looking at the manual the way they describe it is that it means 12, have attached a page from the manual.

i would check your afm, swap it out if you can or even just make sure its plugged in. Check all the wires are fine where they go into the plug, sometimes they ge bent or stretched to much and you need to solder them in

That was one of the first things i changed, played around with the wires and there was no change, unplugged it, surged for a second or so and died, woud not start again, plugged it back in and it fired up but still ran like shit.

no, fuses didnt cross my mind, what one would cause these sorts of troubles?

Just bought a fuel pressure gauge to see if the reg is screwed, any idea what the fuel rail pressure should be?

Got the fuel pressure gauge in, on idle it sits at 38psi when reving goes to around 44psi, videobelow shows the gauge and the smoke it is putting out.

i dont know if this would help or not but when one of my cooler pipes came off thats how my car ran but it wouldnt idle at all it would just die. it looks like car is geting fuel so thats fine. just check all the fuse. there should be a bunch next to the accelerator pedal and the box in the engine bay. check it all.

    • Hey y'all! I'm curious about how y'all go about widebodying your cars. I noticed that when running a square setup, my front wheels are a bit more tucked in than my rear wheels. Not by much, maybe 5-10mm. This leads me to wonder - when I widebody, should I use narrower front flares and wider rear flares? I found a set of 40mm rear flares that I really like, and was thinking of pairing them with some 18mm front flares, but I don't want the car to look strange. How have others done this? Note, I'm in a sedan. Thanks!
    • And if it was anything other than an auto tranny part, it might be a problem. But seeing as all auto trannies belong in the recycling bin, it's fine.
    • I have an R32 Fenix rad. It is good.
    • All the schemas I can see, indicate your typical setup of ATF 'cooler' (read: heat exchanger) in the bottom radiator tank..ie; https://nissan.epc-data.com/stagea/wgnc34/5413-rb25det/engine/214/ ...but I can prattle on a bit here. These trannies have a thermistor in the sump ~ the TCU reads this and 1. bumps the line pressure up when the ATF is 'cold' and 2. prevents the TC lockup clutch from operating, until the ATF comes up to minimum operating temp (keeps the ATF 'churning' through the TC so it heats up quicker) -- trigger point is around 55C. In these conditions, the engine coolant temperature rises faster than the ATF temperature, and also helps heat the ATF up, which is why it's best to think of the in radiator tank setup as a heat exchanger ; the heat can flow in both directions... ...with these trannies, the 'hot' ATF comes out the front banjo bolt, flows through the cooler/heat exchanger, and returns to the box  via the rear banjo bolt. This gets a mention, due to the wildly different opinions wrt running auto trans fluid coolers ~ do you bypass the in radiator tank altogether, or put the cooler inline with the in radiator tank system...and then, do you put the additional cooler before of after the in radiator tank system?... ....fact is the nominal engine operating temp (roughly 75C), happens to be the ideal temperature for the ATF used in these trannies as well (no surprises there), so for the in radiator tank system to actually 'cool' the ATF, the ATF temp has to be hotter than that...lets say 100C -- you've got 25C of 'excess' heat, (slowly) pumping into the 75C coolant. This part of the equation changes drastically, when you've got 100C ATF flowing through an air cooled radiator ; you can move a lot more excess heat, faster ~ it is possible to cool the ATF 'too much' as it were...(climate matters a lot)... ...in an 'ideal' setup, what you're really trying to control here, is flash heating of the ATF, primarily produced by the TC interface. In a perfect world, wrt auto trans oil cooling, you want a dedicated trans cooler with builtin thermostatic valving - they exist. These should be run inline and before the in radiator tank system ~ when 'cold' the valving bypasses the fin stack, allowing the ATF to flow direct to the in radiator tank heat exchanger, so it works 'as intended' with helping heat the ATF up. When 'hot' (iirc it was 50C threshold), the valving shuts forcing the ATF through the cooler fin stack, and onto the in radiator tank heat exchanger...and you sort of think of it as a 'thermal conditioner' of sorts...ie; if you did cool your ATF down to 65C, the coolant will add a little heat, otherwise it works as intended... ...the 'hot' ATF coming from the front bango bolt, is instantiated from the TC when in use, so all/any flash heated oil, flows to the fluid-to-air cooler first, and because of the greater heat differential, you can get rid of this heat fast. Just how big (BTU/h) this cooler needs to be to effectively dissipate this TC flash heat, is the charm...too many variables to discuss here, but I just wanted to point out the nitty-gritty of automatic trans fluid coolers ~ they're a different beastie to what most ppl think of when considering an 'oil cooler'... /3.5cents   
    • Been a busy but productive day. Axle and hubs acquired. All fitted up after a bit of modifying. Need to sort out wider mudguards and running light reflector covers but other than that the trailer is gooood to go !!
