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 guys, long time no post as per usual! It's been a busy year so far, the biggest thing being a new job.  After 28 years in the automotive industry I decided it was time for a change.  I was losing faith in the industry and where it's heading.  Now in a completely different industry (electrical) working for a company that manufacture water pump contollers.  Not as sexy as cars but it's an interesting,  challenging industry. I now don't work Saturdays which is a bonus!  It's still 50-55 hours a week but having Saturdays ack after 28 years of working them is awesome!   No news on the GT-R but i did decide to add some more JDM goodness into my life....           1990 300 ZX.  She's not perfect but for a 35 year old car she ain't bad!  Just going to tidy it up a bit and enjoy it.  It's currently auto but will start stockpiling everything for a manual swap. It WILL distract me even further from the GT-R but im hoping not for too long! It somewhat proves a 6'8" freak can fit in a 300 ZX.  Sort of...  I drove it home from the previous owners house in Melbourne via Black Spur and Merton Gap (2 awesome bits of Victorian twisty road) and it was amazing!  Handles so well!!!   I don't think it would be worthy of a full build page but I'll post up some of the upgrades here if anyone is interested?  Cheers guys!
    • End game is to: - Remove all the slop from old worn parts - Adjust setup so that the wheels actually fit and the car is drivable (currently it is not because of the extreme rubbing on the guards).   Progress over the last couple of days, removed the rear hubs! Next steps: - Buy bushings - Replace bushings/bearings on hub - Reinstall
    • Cracked deck  And other cam snap stuff   
    • A few random issues have popped up since my last update. My WMI pressure sensor failed within about 10 minutes of it seeing liquid. It was a 20$ China special, so I'm not surprised. My name brand replacement should arrive today.  My power steering assist also decided to crap out last weekend. The usual, works for about 60 seconds after starting the car then I lose it. I dusted off my old copy of NDS and connected to the HICAS ECU. Code 4 for assist solenoid.... I tested the solenoid and it's fine.  I knew the day where my HICAS ecu would crap out would come, and I welcome it. It was the last HICAS part on the car that is now in the bin. I've ordered an SSR and I will control the power steering solenoid with my Haltech ecu. It will be nice to have proper speed referenced assist again after all these years.
