i rebuilt my b18a for my crx and recently just started it up. i added a BLOX IM so i removed the FITV cause there isnt a place for it to mount like the factory IM. i just looped the two inlet and outlet together. i also removed the charcoal canister cause i have no emissions in MI. i plugged most of the stuff that ran to the canister except i think a vent for my gas tank. its just a line to the ground right now.

i ran the vacuum just like the rywire diagram that i found on their site for a b16 swap into a crx. idk if that could be the problem but my idle is at 2500 rpms.

the idle would jump up and down before i tore the motor down and i think that was the FITV but now that its gone idk what the problem is.

the only way to get the idle to change is by taking the vacuum hose that hooks to the MAP sensor and blowing or sucking to create more or less vacuum.

i searched and could only find things bout the FITV and a jumping idle. i cant figure this out and i wanna drive my car for the first time this year.

 

 

i dont have a PCV vavle either so i plugged the hose from the breather cahmber and the IM and the idle went down like 1000 rpms. i messed with the vacuum a little more and it went down like 300 more. so now its like 1200 rpms at idle.

idk what the problem is because it idled fine before.

help would be greatly appreciated.
