Matt8v Posted September 22, 2023 Author Share Posted September 22, 2023 I think I've now encountered my first frustration with the 350z. Getting it through the mot, it is having troubles with emissions. Firstly a cam position sensor was changed. Then the spark plugs were found to be toast and changed over for new. Now it's being reported that a coil pack (or more) are knackered but the garage need to find out which ones are toast. I still can't wait to get it back!

Olly350z Posted September 23, 2023 Share Posted September 23, 2023 I'd replace all 6 coilpacks if it was me, that's what I did on mine when it started mucking around. It ran like an absolute dream afterwards, better then it ever had done Euro car parts do an OEM equivalent pack that I kid you not was identical to nissans, even down to the mould lines on the casing. At a fraction of the overall cost... 1 Quote Link to comment Share on other sites More sharing options...

I couldn't work out on Euro Car Parts website for the right one. Is there a different one for the rear or something? If you have a link for what you bought, that would be a massive help 😃 Quote Link to comment Share on other sites More sharing options...
Matt8v Posted September 26, 2023 Author Share Posted September 26, 2023 Just waiting for 6x coilpacks to arrive now at the garage, then re-mot and I can get it back again. Missing this car now, been away for getting on for 3 weeks now. You know it's a good car for you when you miss it! Quote Link to comment Share on other sites More sharing options...
HEADPHONES Posted September 27, 2023 Share Posted September 27, 2023 Coil pack failure seems to be quite common on Zeds. Had 2 fail on me a few months ago. I also opted to change out all 6. Couldn't be doing with the aggro of the others failing soon afterwards. 1 Quote Link to comment Share on other sites More sharing options...
Hansburger Posted September 27, 2023 Share Posted September 27, 2023 Maybe it's also a good thing to do the "Idle Air Volume Relearn" procedure to reset the ECU. It really worked well on my old Z. It drove better then ever and the emissions where also lower then before. MOT wasn't a problem anymore. 3 Quote Link to comment Share on other sites More sharing options...

My garage guy has now carried out this operation and reports a smoother running lots better. Trouble is that the car runs well, then throws a wobbly and the engine management light pops on again. We have changed the 6x spark plugs, 6x coilpacks and now going to swap over the remaining cam position sensors. Painful cost now but will be great service items to get out of the way for the long term. Separately, I've managed to buy a great condition steering wheel. Mine is really worn on the top, this one just needs a minimal clean and good to go! 1 Quote Link to comment Share on other sites More sharing options...

Just bought it a week ago from a salvage auction site, no viewings, just online bidding. Luckily I won and had it transported home. As you can imagine, there is a list as long as my arm of bits to tidy and sort. I've been very lucky that the engine sounds as it should do. Not driven it yet as a front alloy has a crack in it. There's a replacement coming this week. A few photos of how I saw it to bid on! Hey Matt, what a great thread. Keep up the good work! 1 Quote Link to comment Share on other sites More sharing options...

Everything else won't work or only for a short periode of time. And just a guess. Is everything alright with the timingchain? Does it make noise with the start? No gasleaks? No gaskets blown? Intake or exhaust? Which code does it have when the light is on? Quote Link to comment Share on other sites More sharing options...

Thought about the timing chain but it isn't noisy or rattly on start. It doesn't look like any gasleaks. I've changed the intake back to the standard box. Exhaust manifold and cats remain the same but everything back is brand new. Chatting with my mate, he wonders if the injectors could be dirty from age/ standing for a while. So he suggests cleaning the injectors, new fuel filter etc. Quote Link to comment Share on other sites More sharing options...

Matt8v Posted November 20, 2023 Author Share Posted November 20, 2023 Hey guys I forgot to update earlier but my 350 is home now. All happy that I have a new mot and a few jobs completed. I now have a beautiful Fujitsubo stainless exhaust. Quiet at idle and round town, then nicely howls when giving it beans. No droning at all, a lovely bit of kit. The only way that I can describe the tips, is ridiculous! I love them. They are huge, I can lose my fist inside them! 😄 Other works- 6x new sparkplugs 6x new coilpacks 1x new cam position sensor 6x injectors removed, cleaned & refitted 2x front lower suspension bushes Driving is great, picks up really quickly and hoofs along quick for me. This is the fastest car I've had, so no real supercar speeds to refer to. 4 Quote Link to comment Share on other sites More sharing options...

Matt8v Posted February 20 Author Share Posted February 20 Not posted for a while. Thought I'd share my silly wheel refurb with all you folks. The GT4 alloys were looking very tired and scuffed from when I bought this one. I could have gone for factory shadow silver but its not worth worrying about being a concourse winner. This is a bit of fun! Topped off with £6.49 Nismo stickers from ebay to break up the white. Very Marmite, some don't like them. One said it was too PlayStation for them while my 13yr lad loves them! That's a win for me then! 2 Quote Link to comment Share on other sites More sharing options...
rabbitstew Posted February 21 Share Posted February 21 Wheels look ace! I did white wheels on one of my cars once and they look great but are a mission to keep clean! Plenty of poor boys wheel sealant on them!!! 1 Quote Link to comment Share on other sites More sharing options...

marzman Posted February 21 Share Posted February 21 Enjoyed reading this thread, good effort! If the smoke smell is still an issue, pick up one of those air con bomb things that you set off in the car and leave your blower on full blast for 20 mins... have worked a treat for me in smoker-owned cars. https://www.amazon.co.uk/s?k=air+con+bomb&crid=1GOJ16DU63JFK&sprefix=air+con+bomb%2Caps%2C208&ref=nb_sb_noss_1 1 Quote Link to comment Share on other sites More sharing options...

I'll have a look at that link, the smell is very much less now but just got the odd whiff from time to time. Quote Link to comment Share on other sites More sharing options...
