Was the check engine light on at all? How many KM's has the car done and what is the service history like? Maybe the timing chain has stretched resulting in the aforementioned trouble codes.

The engine light never came on, when I had the ticking issue. It would only come on when I unplugged the blue plug on the driver side. When it was unplugged, the ticking noise would go away but the engine light would come on. then plug it back in and drive the car for a few days, then the engine light would turn off.

Then I started to have stalling issue. The car would stall at the lights, even sometimes while driving, happened once on the freeway. engine stalled, all the lights came on for a split second and then started again by itself. I changed the oil pump thinking that it might have been the cause, but wasn't.

Then the vibration started. when it started, the car was no longer stalling, and the engine was not ticking at all. It would only vibrate in idle, when you drive the car, it would run nice and smooth.

This Friday, I was driving home from work and the damn thing stalled (hadn't stalled since that vibration started-more than 2 weeks). Initially the car didn't start. I got out and sat there for about 10 minutes to figure out what to do. then when I got back in to try one more time before calling a tow truck, it started.

The car had 108.000km on the clock if it's the correct number.

has been serviced every 10.000km since I got it (it was 47.000km when I got it)

the timing chain doesn't make any noise at all. Even when I had that ticking noise, it wasn't the timing chain.

You need to get the codes read again. Nissan would have read every code logged since the last ecu reset, so now it will just be the sensor error responsible for the stalling.

Changing every sensor without diagnosing the fault is just crazy. Nissan just want all your cash.

Drop in if you like and I will check the codes. (free of charge) You can decide what you want to do after that. I don't imagine it's very safe driving it far, the way it is atm.

Hey guys, i have a 2003 300gt and i have noticed that it idles a little harsh. Im not having as many issues as NISMO-61, my car has never stalled. it has 45,000 kms, and at idle its a tad harsh. i have also had a few misfires.

its been suggested to change the spark plugs, (but they should be fine for those kms) and change the oxygen sensor.

what are your thoughts?

Thanks

There is a good chance the plugs are shot, after all they are 10 years old. The o2 sensor can be easily tested for correct operation. Perhaps the injectors need a clean also?

I highly doubt your km's are correct, looks like the importer got greedy with the odo trim.

Im going to clean the plenum, and have a look at the plugs. if they look foul i will replace them. But i think cleaning the plenum will help a lot. i will also be able to see how much crud there is and relate that to kms. i know heaps of these are wound back, but i have the original books that came with the car and it includes service history. it shows it was serviced very regularly. and my importer couldnt have wound them back because i saw the car as soon as it arrived. it all seems to add up.
and i might put through some injector cleaner

thanks for the tips

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
