WHITEPRINCESS : just my opinion, probably ur mechanic knows the problem, but said O2 was faulty so he charged u more, and fixed the lil problem caused ur rough idle.

Rough idle could be lots of things,

Dirty Air Filter, AFM Conection?, or Spark Plug etc,

Clean them and see what happen?

To reset eCU...Instructions:

- FUSE box driver side kick panel, (remove it)

- look under, u should see a grey plug,

- there should be 2 wires on its own,

- short circuit it for 2 second,

ecu should be reset, check for engine light flash.

Hope it helps,

cheers,

also want to check your aac valve mine was idleing a bit rough doin thatup and down thing sometimes when i stopped at intersections

i ended up pulling the connecter off the aac valve and idles smooth as

i have also replaced my o2 senser and spark plugs, only because my car was running rich as, but wasnt really the cause of makin my idle go all stupid

just my opinion, probably ur mechanic knows the problem, but said O2 was faulty so he charged u more, and fixed the lil problem caused ur rough idle.

the guy was quite honest about what he was doing. i saw what readings he was getting on his diagnostic computer before, it was showing the O2 sensor readings 0.01~0.03 and that's not right - i also have r33 engine manual that confirms that O2 sensor should be giving out something like this 0.3~1.0 from what i can remember. also one other sensor was always saying 'rich' where it should be changing to 'lean' when the car was reved... i know for a fact that when i came in my car was stalling here and there, i saw the guy installing the O2 sensor (no hidden magic there) and when i drove out of the garage 20 mins later, the car was running perfect...

thanks for your feedback though :)

i guess my recommendation would be to find a person who can connect up a diagnostic computer to YOUR car, read the reading and understand them so then they will tell you what's wrong with the car... becuase rough idle can be caused by many things as many people said, in my case it was O2 sensor but on another skyline it could be dirty something or rather etc etc.

Thanks for the info guys. I've been searching around and seems to be the AFM. One other thing i should say is if i open the oil cap while the car is idling, the idle drops quite a bit and the car sounds like its going to stall? Vacuum problem maybe?

I noticed this the other day on mine. Is this Normal?

    • Dropped the MX5 of this morning to get the hardtop colour matched and some PDR done, they are also going to give it a buff to remove some "stubborn" swirl marks and light scratches in the clear coat Over the last few months the poor little thing has copped some shopping centre car park abuse, I try to not park in them, but hitting Westfield's a few times over the last few months has taken its toll, nothing really bad, but enough of a trigger for a "while we're in there" thingie  Once it's back and all the one colour, with a few dents and mark's removed I'll give some of these products a go and see what they're like  
    • A locally delivered Infiniti have remote start installed but don't come with the remote start key. You need a new remote start key and they just need it programed. And this is different to making/programing a new key that just starts the car.  
    • Cheers, and cheers for sharing so much of the build and also sharing the glimpse of what turns out to bring a lot of us poor decision makers together haha.  I do recommend learning more about how to manage it, if not considering getting a  formal diagnosis.  The discussion with the psychiatrist I got my diagnosis through was quite eye opening, things I'd not even considered to be ADHD related and hadn't mentioned were things she asked about out of the blue and were common themes with people with my flavour of ADHD.   It's not a label for people who are hyperactive and ill-attentive, there's more to it than that and some of it can be much more challenging or damaging - though there are of course two sides to the thing, and a lot of the stuff we have to go through and work on to live with it make us effectively "better" at other things as well. Aside from the fact that there is some argument I could have a bit of ASD seasoning in there (came up during the diagnosis, and neurodiverse things seem to not stay as a cookie cut) I suspect you need to learn more about ADHD if you are puzzled about how hyperfocus could possibly apply.  I *do* personally use "superpower" with quotes deliberately, but it's 100% an ADHD thing due to the exact reason that lack of focus is also an ADHD thing... Loosely speaking the inattentive side of ADHD isn't the inability to focus, it's the inability to control where the focus goes.  Not being able to sleep because brain is more interested in thinking about a stupid thing I said to a girl I liked 30 years ago, not being able to focus on work because my brain is more keen on putting together the torque management strategy we're going to try out with a drag car next weekend, not being able to focus on a conversation with someone I WANT to listen to and respect because there is a flickering light in my peripheral vision.    If I could just stop work and build the torque management setup right there and then I'd not hear anything else until it was done.  
    • Maybe you should do some more reading.  Google positive effects of ADHD and you'll get your answers.  One of my personal downsides of ADHD has been talking before I think.   Maybe you have it too?
