IAA valve

[nissanfanatic]

Ive read the posts at 240sx.org and I'm not quite sure where the valve is exactly. Is it the one with a cable that runs to the throttle body. Or is it the one of the bov or pressure reading looking things under the rear of the intake manifold. I ask because whenever i put a load on the engine, such as accelerating quickly, and take it up to about 5k, after i let off the gas it will drop quickly and sometimes even shut off.

mine drops quickly, but never shuts off, gets low tho, like 200rpm, id be happy to find out why, and how i can fix it

it is under the rear of the intake but doesn't have any vaccum lines. you may need to clean it or reset the idle screw open more. if you open the screw then you will probably need to check you timing again. those stupid valvles have caused me many problems.

Ill try that. Thanks!

Oh and which way adjusts what. does clockwise add more fuel and counter add air or what. Thanks!

sorry to bring up such an old thread,

but where is that screw that adjusts the idle?
