Need help 5 of the spark plugs look ok with the white or gray color tip but there's one spark plug on cylinder 6 by the throttle body is totally black on the tip like its foul. Upon inspection of cylinder 6 through that small spark plug hole is wetness an as I touch it. It smell like fuel. Am I experiencing a fuel injector leak on this cylinder an if so does these v35 250gt skyline use the Same fuel injectors. Car starts fine but idle rough at low rpm, black fire also strong exhaust fumes an lack of power am experiencing

This jogged my memory to post up these pics of the VQ25det plug, DD plug and whatever plug the last mech installed into the 25DD I have here.

Blanking off my egr dropped fuel consumption from 12.5l/100km to 10.6l/100km city driving. And no more soot.

probably needs an idle air volume re-learn.. assuming the VQ30 has this opiton like the VQ35 does.

Tiptronic mode ... even if it says 3rd gear on the dash it doesnt mean its in 3rd gear. It is designed to change back to second and first if youre not moving fast enough for the gear to be used. Its not a true manual selection unfortunately.

Ps.. there are mechanics out there with consult tools that will give you an explanation. I know a guy in adelaide who has a consult tool that will read all the diagnostics but still couldnt help me with a transmission fault code. Then i found a mobile auto electrician that had a consult tool which gave me a detailed explanation of all faults. Then i visited a transmission specialist that had even better knowledge.

Unfortunately you will have to visit various workshops until one of them has a tool that works with your car. And it will prob cost $60 per visit if theyre mobile mechanics

ok you guy i am experiencing a rich condition and i have remove all six spark plugs and have discovered that cylinder six below the trottle body spark plug have a foul look black black tip but clean around the threads. the other 5 look like normal spark plugs with the white or gray color tip. anyway upon looking in cylinder 6 hole was some wetness inside. i push a slim cloth in the hole an upon removing the cloth it was fuel. AM I HAVING A LEAKING FUEL INJECTOR ON CYLINDER 6 THATS IS CAUSING ME TO RUN RICH CAUSE I ALSO SMELLING FUEL OUT OF MY EXHAUST AND ROUGH IDLE AND LOSS OF POWER.

Take them to an injector specialist and get them tested if you are worried.

If the injectors are fine, you likely have a short in the wire to the ecu, or the ecu is faulty.

Is there any water dripping on the ecu, or water damage inside it?

I think you're out of your depth here. IMHO replacing the injectors on a Di engine is something you probably should leave to someone who doesn't need to ask these sorts of questions. Why not get your injectors flow tested by an expert in Di? Most of the Diesel specialists should be able to help here. Otherwise you could be replacing something that doen't need replacing, and I believe it won't be cheap based on what I was told. Are you sure the issues you're having in that cylinder aren't due to a coil pack breaking down or something different?

My 350GT will do the same if I'm not moving fast enough, but it will always show what gear it is in on the dash even when it downshifts on it's own. Never had it show as being in 3rd when it's actually in 2nd or anything.

Trust me I know its a fuel injector leaking all six coil packs are brand new. Meet fuel in the park plug hole. Plus this the third time changing single foul spark plug

What coil packs are you using, and what plugs?

The chance a direct injector is stuck open and leaking is slim. You can't remove them easily, they use piston ring style seals around them. They are very hard to remove and refit for a reason, as they need to hold in thousands of psi pressure on combustion. As I have said, get them done by a specialist.

The early 35s only show the highest possible gear selected, not the gear it automatically selects if you go too slow.

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      R32 gtr transmission strength, billet plate

      By cosline · Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz · Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
