Jennie 1990 Posted November 12, 2012 Share Posted November 12, 2012 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.

iwanta34gtr Posted November 12, 2012 Share Posted November 12, 2012 (edited) 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.

MBS206 Posted November 12, 2012 Share Posted November 12, 2012 I believe you will find in an R34 that that is a dieing of the coil packs. Link to comment https://www.sau.com.au/forums/topic/413521-diagnostic-scan-code-21/#findComment-6622206 Share on other sites More sharing options...
FeZ25 Posted November 12, 2012 Share Posted November 12, 2012 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.

Jennie 1990 Posted November 13, 2012 Author Share Posted November 13, 2012 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! :-) Link to comment https://www.sau.com.au/forums/topic/413521-diagnostic-scan-code-21/#findComment-6622831 Share on other sites More sharing options...
oweban Posted November 13, 2012 Share Posted November 13, 2012 yep, yellowjackets if you don't have serious power - i had them in at 201rwkw with no problems.

Jennie 1990 Posted November 13, 2012 Author Share Posted November 13, 2012 (edited) 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! :-) Edited November 13, 2012 by Jennie 1990 Link to comment https://www.sau.com.au/forums/topic/413521-diagnostic-scan-code-21/#findComment-6623740 Share on other sites More sharing options...
oweban Posted November 13, 2012 Share Posted November 13, 2012 Definitely comes with time - I've had my liner almost 6 years now and I still learn new stuff all the time.

Jennie 1990 Posted November 14, 2012 Author Share Posted November 14, 2012 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!

Jennie 1990 Posted November 14, 2012 Author Share Posted November 14, 2012 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!
