R32 Gtr Running Poorly...help

[IOWNU]

Hey everyone,

My 32 GTR has a problem, it has all your basic mods, n1 turbos etc etc.

Today it started doing a few funny things. When I a accelerate, the car might hit say, 2500-3000 rpm then start stuttering/hesitating,

i'll put it in 2nd, and it might hit around 4000rpm and just cut out, as in stop accelerating all of a sudden. If I play around with the gears,

the car will get moving again.

And sometimes, it runs real good, in 1st/2nd, but 30 secs later it will have the hesitating problem, the car gets stuck at a certain RPM and refuses to budge,

unless I shift up or down. And it even almost stalled once, revs dropped to 0, i tapped the accelerator right before it would have stalled. It is strange that i cuts out completely,

usually, if a car pings, you keep accelerating, it will hesitate, but get through the rev range. Whereas in this case, it does not.

Going to the mechanic tomorrow, but has anyone had this problem before, in case it is something simple I can fix.

Thanks.

You may have dodgy afm/'s. next time it does it, try wiggling the afm plugs and see if that changes it.

If it does there is a diy fixit thread on here somewhere.

Why dont you do a diagnostic search, thats what its there for.

Thanks for the advice guys.

I was thinking AFM or Sparkies.

Will take it to mechanic to get the diagnostics check tomorrow, its too hot today in Melbourne, should have left early lol.

umm sounds very similar to my issue and i have followed the tut on cleaning the afm and checking the solder.. still happening.. does anyone know voltage the afms should be seeing normally

Just change the AFM, no point stuffing around with a stuffed AFM.

I had to change 1 and now its running fine.

Thanks for the help guys.

the power supply to the ignitor and the earth wire at the back near the ignitor...check those harnesses..had the same problem with same symptoms with my old GTR....bcos i was getting the coil cover resprayed had to move the wires and cos its older car the wires can become hard...and think thats was caused mine to cut out etc as above

hope that helps if it isnt the AFM
