Pretty simple with Ace's instructions, trouble is the lack of space to work. HEAVILY recommended is the upgraded harness, as the old ones (and OEM replacements) are NOT moisture-shielded and is the cause of your issue(s) most likely unless the IACV guts are caked. Z1 and others all carry the upgraded harness IIRC, not too expensive either.jdm86.na wrote: ↑Fri Aug 17, 2018 10:03 amHi, I'm new to the forum and have a 1990 z32 300zx NA. I am hoping to replace my IACV setup - I have the part already - and have been looking for a good guide on the replacement process.
I have already searched the forum, and if it exists, I wasn't able to find it.
I also have the online FSM and am looking through that.
Just hoping someone might have some more information to point me towards.
Thanks
