can anyone help???

my rb 20 has a bit of an unstable idle and sputters every now an then.

it is pretty standard (only a 3" turbo back)

would an ECU reset fix this or do i need to get it tuned or (even worse) is there something seriously wrong with it????

thanks for your help.

sorry to hijack but HOW THE jolly heck do you adjust idles on a Rb20????

EDIT i read the post ive figured it out now ill try it on the weekend.

Theres an idle screw on the AAC Valve. If your standing at the front of your car looking over the engine it sits on the end of your plenium and the screw faces your left.

i had crap idle and fixed it:

AAC valve cleaning, throttle body cleaning

and also I had a inlet manifold gasket leak, so replaced that gasket and just perfect idle all the time now

Nice work. How did you spot the inlet manifold leak? Could you hear it? Did you use a vacuum gauge?

Cheers

plus the R32 acc valve is slightly different ==>

there is only one hose connected to the valve and only one electrical clip.

the valve also has 4 bolts.

another difference is that the spring and all that bizzo is insode the solinoide cover. mine was caked in crap.
