The problem with my Afm required it to be internally repaired (the solder joints on the inside of the plug to the afm's circuit board Under that square black cover) a clean wont do unfortunately.

It would be better for you to swap it with a known good working unit to test.

i spoke to dr-drift aka sam and hes on to something, he said that maybe theres a problem with the solinoids that are on the hicas steering,now that would explain why it only does it to the left, maybe theres a short or it robbing power away from the fuel pump??? sound logical

well i unpluged the computer under the parcelself and it still did it,and i think the hicas system is hydraulic. Sooo where do i go from here??? now i know it doesent do it in reverse on when u go forward,and it even does it when you going walking pace to the left, soooo maybe its some sensors somewhere, is there any sensors in the steering rack????? also when u hear backfiring noise that mean rich fuel mixtures cause thats what its doing after the steering wheel goes back to straight, which make me think that maybe its not playing with fuel pump but maybe spark??? does that sound right???

Sounds like something to do with the fuel pump..or even something silly like fuel line being twisted or pinched or something as you turn. Check your fuel filter as well, can't hurt to replace.

Backfiring is overly rich yes.. i get it with low-grade fuel sometimes as well.

The skyline fuel filters are replace type only Z200 I think.

You in your profile state your car is an r31 coupe is this the Rb20 equiped model? if so on the drivers side of the engine bay is all the soildnoids and hydrolic sensors May be you could un plug them an see if the car still plays up also thats the same side as the fuel lines check as someone else stated that the fuel line is not fouling with the steering rack(getteing pinched) . Still dont rule out the Afm until you have swapped it with a known working unit.

well i changed the sparkplugs and its kinda better now,but i found that the 2 plugs that go into the igniter box thing at the back of the engine,when i fiddle around with them then it stops, i tried to do some fixing to the plugs but its a no go,so which makes me now think its the igniter pack thing, does this thing stuff up much???

    • Hi 🙋‍♂️. Just bought my Unicorn but the interior need some minor work so it would match my expectations ;). I noticed it is hard to get used oem floor mats in good condition so i started to dig if there's any chance to buy set of new ones. I found two websites - nengun and amayama and it looks like one can still buy factory new floor mats in Japan, but thers a small issue. Some mats (i assume genuine, oem ones) are marked as G4900 and these are "discontinued". The ones you can buy are marked as G4911 but i have no idea if these are also oem, made by other producer or some lower quality replacements that looks entirely different. Can anyone help? 😃  P.s. there is also some strange indication - 0V005, 0V015 and 0V505. Any idea what does it mean? Would appreciate any help with this 🙏
    • Hi, Marek here 🙋‍♂️. I finally fulfilled my longtime dream - recently bought Stagea and now waiting for it to arrive in Poland. There's only few of these in my country, and one of the owners  recommended mi this forum as a source of all the info i'd need since now i own one  so here i am.  
    • Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though
    • and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.  
    • Oh, you are right. But, in Australia E10 is based on 91RON fuel and ends up being 94RON. Hence it being the cheaper option for economy cars. The more performance oriented cars go for the 98RON fuel that has no ethanol mixed in. The only step up we have left then at some petrol stations is E85.
