Injector replacements

I might need new injectors. When I had a different idle issue in 2010, I got a set of 6 Deatschwerks remanufactured from ConceptZ at $365 for 6 $61 each. These are still available at $529 / $88. SO I had a look round and there are others down to around $62 for AUD remanufactured. Then I looked on Ebay and found https://www.ebay.co.uk/itm/6x-NISSAN-300ZX-FAIRLADY-INFINITY-J30-MAXIMA-SENTRA-26lb-270cc-FUEL-INJECTORS/222825765310?fits=Plat_Gen%3AZ32&hash=item33e17359be:g:40IAAOSwOn1aeGPN which claim to be new JECS for £89 for all 6! If something looks cheap, it often is - has anyone had any experience with these?

Cheers

    £89 for 6 !!!! Personally I wouldn't go near them. With there being issues with Z1 and warranty issues lately I'd be more inclined to talk to Greg at Protuner. He markets his own purpose built injectors I believe and with him being UK based it should be far more straight forward to resolve any after sales issues.

    What makes you think you have an injector issue ?

    Well, before the MAF died https://www.300zx.co.uk/forums/showthread.php?190301-Intermittent-rough-idling-next-diagnostic-steps&p=1989513&viewfull=1#post1989513 the next steps were to follow the rest of your advice. Got plugs, fuel filter. O2 Sensors on their way. From CAS sensor variation, timing instability, Simon thinks the ECU is constantly trying to compensate for something. One possible cause is a dirty injector or 2. Now the last time that happened to me (the blue S3 NA), the ECU revved high at idle to compensate for the dud injector I had. So that's not the case here.

     

    However, if we eliminate the things in your advice and it's still not right, then it might be injectors - so I was doing some desk research to be forewarned and have something lined up if needed.

     

    But look what arrived yesterday and is now the first job to see what happens.
