Are the iacv-aac valve and AAC/IACV valve interchangable in all years 240sx 91 to 98 ?
My idle goes crazy sometime and fluctuate , At least I am not running rich like I used to , The plugs are the same and even the connectors coulors are the same .
Anyway , I was planing of replacing the lower intake manifold but if all valves are the same then I can just swap them from my 98 intake manifold .
Can someone please confirm this .
thanx for reading .
