Hey everyone.

Having some major problems with my S2 R33 Skyline Gts-t.

Started off as just a small missfire under 15psi so I had the plugs done coils checked and new Cas put in by a mechanic got it back and it was backfiring and run awful so i took it another shop in melb who i was recommend to due to the wolf 3d ecu they trimmed the fuel changed the plugs again and looked over coils run like a dream for about 2 day and since has developed a lumpy note which sound like a wrx and a very bad missfire through the whole rev range and a few days ago it started stalling when i slowed down nearly as soon as i put the clutch in.

If anyone has any ideas on what could be wrong that would be great.

Cheers

Right .. Well I dont know much but I know a WRX sounding skyline is coils .. so they need to be replaced with either new coils or spitfires.. from what i hear spits are better ..

I was reading today that gtr coils are the best....but costs are higher...therefore you will need to get spitfires...when replacing yours.

On the other hand if coils were checked.....then either your crank angle sensor or something else is wrong....your timing is being thrown out some-how.

Borrow some coils if you don't want to buy them...this will let you know straight away.

I have a set...if you want to plug them in and check...(RB26..are they the same?)I think they maybe.

Cheers.

Done both of that lol, it already has splitfires and had a new cas put in about 3 weeks ago so i have

no idea what it could be, but I have lookin around and the conectors to the coils look really crappy do

you think could have anything to do with it?

Ignitor and cables get alot of heat and can be damaged....also you could be missing because the ignitor is not earthed properly.....Have you got the cover off and the ignitor loose or is it screwed down on cover?

The cost of a new ignitor plus cables is big bucks from nissan...

You will need a car elec. to rewire the whole loom,,,this is a cheaper option if the ignitor is good...

Cant see any other reason this is happening......have you checked your injectors?

Bad pump,injectors and afm's can also play around with missing problems and with afm's running problems...

Yea i was thinking of having a elec lookin at the wires and also because it is a series 2 they dont have ignitor packs which is why u cant put series 1 coils in a series 2, but thanks for the advise i will have 2 have the afm looked at as i think it shouldn't b the injectors or fuel pump due to them being aftermarket parts.

Found the problem, although 2 well know shops said my coils where in good order and because they are splitfire they will be fine it turned out 2 of them were rooted and both shops put wrong heat range plugs in, so put new plugs and coils in car back 2 running 15psi without a worries so thanks for imput about the coils guys.

Cheers

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      By Bireley_32 · Posted

      Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
