Not sure if this is what you did, but check here:

Here's another solution on 240sx.org faq:

I have a 1991 240SX. I had this idle irregularity problem and took the car to the dealer after I saved some enough money. After several hours of head-scratching, they figured out the IAA valve (which controls the air intake to the fuel injector) was the problem. All they did was to establish an extra grounding wire and also covered the original connecting cable with plastic tape to secure the proper grounding. Now I don't have to fix my eyes to the tachometer each time I press the clutch pedal. It was a really irritating experience and cost about $120, which I think worth it.

Hope this helps...
