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???

    • I can ship Nismo floor mats to you: https://www.oemsoko.co.jp/products/nismo-floor-mats-for-skyline-r33-bcnr33-stagea-wgnc34?_pos=1&_sid=9278c1467&_ss=r  
    • Here's the link: https://www.amayama.com/en/genuine-catalogs/epc/nissan-japan/stagea/wgnc34/6642/misc/G49?frame_no=WGNC34-137122 What you think about it? The same product i found on nengun: https://www.nengun.com/oem/parts/40567/MiPwn5qAMfCfmpxHNDnwn5q9MDAx8J-QiW9sZC1qcC0xMTAtRzQ5LS0wMDE/Floor+Carpet+%2F+Mat+2/0688339eba149c19 Bot i have spoken to 😅 ensured me, that mats are 100% original, oem product. I have my doubts. I also heard what you mentioned, that nengun often offers items that are actual not available... On the other hand mats i found on japanese yahoo or ebay are in poor condition and still quite expensive so i'd rather wait for some better offers. My location - Poland. We literaly don't have ANY market for used Stagea parts so need to search outside Europe.
    • You can’t see much on the other side as the lcd is there I don’t think it’s the same as the m33 beside it as the markings on top is not the same was hoping someone had a good quality photo or if they just happened to have the unit in hand, quickly take the cover off and take a photo to clearly show the marking on top to identify the diode   the unit is currently with an electronics repair shop so I can’t take another photo at the moment hopefully they are smart enough to know if it’s a zener diode or not
    • I'd be very surprised if you can buy new OEM mats. But if you can, I want some too!  Do you have links to the variations you found? Also, where are you located? I found that Nengun is happy to list items to purchase but when you do buy them you'll get an email that it's actually discontinued. As far as I know the variations in floor mats are different colour schemes as well as automatic and manual having a slightly different shape. The automatic ones fit into a manual car without issues, but I think you'd have trouble fitting the other way around. I have photos that show the shape difference if you care. FWIW I bought sets of used floor mats in decent condition at yahoo auctions.
    • 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 🙏
