Acc Valve Operations On An R33 Gtst

[WogsRus]

Well i decided to pull my ACC valve off last night, basically because of the ongoing cold start issues.

The reason i did was that eaven if i wound the screw all the way in on the ACC valve, i couldn't get a lower RPM then say 600.

SO cleaned it up, pluged it up and all good workes well, the valve was clean, but i still can only get to 600 rpm.

NO i don't want it to idle at 600 rpm, it was just an observation.

I have set the idle as per procedure and seams to hold ok, but if i pull the ACC valve plug off the car will die, i suspect that this is correct?

I have tested the ACC valve with the multimeter and the computer and all work OK, as per spec.

Is there any way that one can test if the ACC valve operation is abnormal.

ALSO found that my Cold start valve is a bit stuffed, if you put it in the fridge it only opens half way, so it is never fully open when cold. I kinda bodged it up to do so, and it work a bit better, but need a new one.

Any idea on cost????????

The car still starts like a dog, leaning more to fuel injectors. I am going to deperesurise the system, and then push compressed air through the system to remove all fuel and see how we go.

hey man theres some info in the DIY cleaning aac valve section but i think you probably have read it.

cant you adjust it from the ecu as well to make it a bit lower if you wanted to test it.

S2 ecus don't have the screw thing in them, nor the LED for error checking.

Read the DIY, but that is no help, i have many other issues. LOL.
