Got another FYI for the board, if you’re having a hard time sourcing an Idle Air Control Valve for your 90-91 DA9 at local auto part stores (O’Reilly’s and Advance Auto confirmed) look for an 89 Integra IACV, it bolts right up and functions normally.
They’re also a helluva lot cheaper on say eBay.
Again, I apologize if this is redundant or well known, I just want to help anyone in the future who may come across this, the parts you need are out there, you just need to know what to look for.
Regards,
