Hi guys and girls.

My check engine light came on Friday and has been off and on since. I rushed to my mechanic today to have a diagnostic test run and have found code 21.

Can anyone recommend someone who can help me out who won't stuff me around or rip me off?

I have an idea of what needs to be done but would like to go to someone who knows R34's well.

Unfortunatly my mechanic is unable to assist me further and I am looking to find another that I know people trust.

I would love to hear some positive experiences from more knowledgable enthusiasts such as yourselves.

Thanks in advance.

At work at the moment but from memory - consult error 21 is ignition, most likely coil packs?

PM sent regarding mechanic who has both, the knowledge and the parts readily available.

Cheers.

Just thinking - has anything been tried so far in an attempt to fix?

Let me know if you need a hand.

If you're after new coilpacks I can't recommend yellowjackets enough.

Mine were on the way out, giving me a horrid misfire under any kind of load. Popped the yellowjackets in and it's been great since. $440 delivered if I remember correctly. Really simple job too.

Thanks guys! It's most likely the coilpacks unfortunatly. $$$ :-(

Organised to have her looked at this afternoon. Thanks Andrew. Going to get a professional to do it as I would probably do it all wrong.

Just want to pay the money and get it done and move on. :-)

I'll let you know how it all goes!

Thanks for all the help! :-)

Well my baby has spent the night at the mechanics. New coilpacks coming in today also having the sparkplugs changed while I'm at it. Wasn't too serious. We found that the coilpack for cylinder 5 was being lazy! Look forward to picking her up this afternoon! :-)

Thanks again for all the support. I hope to one day be as knowledgable as you guys. Clearly I have a lot to learn! :-)

Thanks Owen. I feel a bit better about it all now. Well the learning has begun! :-)

Today was a no go though. The parts came in late this afternoon damaged in transit. :-(

New coil packs on the way express good to go for tomorrow! So I'll head there again after work. Couldn't spend another day without her. Looking forward to tomorrow afternoon when she'll be back and better then ever!

Hey Marsss! Hope you're well.

Coil packs being sent from a supplier in Queensland not Japan.

I try to always keep an open mind but after doing some investigation I look forward to seeing what this afternoon has in store for me!

Nice one! and "overnight parts from Japan hey? yr doing well....

why do people call them "liners"??? :rant: they're not liners.. if anything, they're "lines" :domokun:

carry on

Why do people call service stations "servos" if anything they should be called "services"

Or even more so, bottle-o's, "bottles" makes a lot more sense!

      RB26 turbo oil banjo bolts

      By sunsetR33 · Posted

      I found parts on EFI Solutions webshop that seemed to be the accurate ones. I haven't gotten around to fitting the turbos back on the car yet since I still have to deal with the shitty crack in the engine block. But I'm confident that the bolts I ordered will fit. According to EFI they are also 7-16/24. The reason M11x1 got involved here is because it is apparently very similar to 7-16/24.

      R33 general questions

      By Kaptain · Posted

      Well, to be fair to the car I've driven it daily for almost a decade now, although in that time only put on 50k, as it just recently passed 100k miles early this year. For the most part its been fine because I've been able to source parts from AUS like jacks jdm and a few places in Japan, some things like pads have been easy since 300z pads swap right in... I realize its probably at that time in its life i should find a new DD (but I rent and only have so much space, no garage) so new cars just complicate things. As it is older though, I recognize its about that time as with my '67 GTO to maybe side step and find an alternative, but if i can keep driving it... I want to.   That said, I may just look into a local shop that might be able to, problem is the mechanic I work with has limited space as a mom and pop operation, and he's a busy busy man, so id need to find out if he can keep the car in the meantime, which may or may not be practical for him. Maybe I'll just buy one off jacks jdm and get that refurbed /shrug.. just looking at options and what others may have to offer for advice on the matter. Like I said, its hard finding people around here who actually have one, I've had mine 9 and a half years and I've met 3 others, and they are all military, one was oem from 95 with 30k miles (rip that car... guy got hit after someone crossed s double yellow, totaled it)

      WGNC34 Rear springs

      By zoomzoom · Posted

      I've noticed my rear springs sag a bit compared to the fronts. I have stock springs and KYB struts. The front wheels are pretty consistent in their ride height, but compared to the front wheels, one of the rears sits 20mm lower, and the other 40mm lower. This negatively affects the ground clearance, and also angles the headlights up. What are some some economical options for new springs? Or information like good spring rates, lengths  in order to find a suitable replacement etc Far from lowering the car, I'd prefer to raise it a bit to keep it ground clearance friendly.
