idle problem- IAA valve questions

[spitz7985]

First of all, I have the typical 240sx idle problem and I'm finally going to track it down and fix it. I read in the 240sx.org FAQ that it is probly the IAA valve. So, do I need to replace it? That would suck, it's $130 from Autozone. Most importantly, where is it? I read that someone had an IAA problem and all they did was establish an extra grounding wire and it was fixed. Is this a possibility?

Thanks,Brandon

with electrical there are variables to failure but yes a ground problem could be it. If its a mechanical failure it could be the valve it self. some people have cleaned it and been successful in straightening up the idle.

Where is the valve located?

Thanks, btw.

On the S-14 there is a fuse for Ecm functions that can blow and cause the car to idle real bad and it will through a bunch of codes I not to familiar with the S-13 but I would check all your fuses, It might be a simple fix???Thanks
