hi, my name's adam, and i have idle irregularity issues.
i did a lot of searching, and although i have found a lot of info on iaa related problems, one big important piece of information remains unknown: where IS the IAA valve?! after reading the following, i want to try to establish another ground wire.
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.
so, if someone could just tell me whre the damn thing is... please... i'd be eternally grateful. FSM scans would be even better, but that may be pushing it...
