geez i get no love. can ya at least tell me where these sensors are located i did a few searchs and i cant find anything.

 

what's your setup? iacv (or eacv) is located behind the intake manifold. is your vtec wired correctly?

 

aight i dont know what the hell i have. i bought this car for my bro and our cuyrrent setup right now is type r head with a gsr block. i know know if i have iacv or eacv. how would i know. also the vtech spool soleniod whats the deal with that? thanks

 

The VTEC solenoid valve is mounted to the side of the head, sorta beyond the end of the exhaust camshaft. The IACV is at the throttle body.

 

where can i get both of those sensors beside the acura thanks.
