So i have a cel on and checked to see what code i had and po 505 came up . So i have a b16a2 obd 2 motor in a em1 . After doing some research in this code i found out that maybe i have a vacumm leak. I read that i have to disconnect my intake and i will see two hoses on the left side by the firewall on my tb. Well i did that and i dont see no hoses. I only see a hose coming from the iacv to the fitv . Now i know that it aint those hoses cause they have coolant in them. So where else am i suppose to look to see if infact i do have a vacumm leak.

 

Do you have an idle problem? If so, describe it.

If you reset the ECU, does P0505 return?

If you have a stock B16a2, it does not have an FITV.

 

Ok sorry about the problem it idles between 1000 rpm and 2000 rpm . I reset it already but yes it does co e back . I even bleed the system thinkin i had air in it. Sometimes the idle surges up to 2000 rpm and u can hear the motor reving. Ok if i dont have a fitv then are them the hose that i have to check?

 

You can shoot some brake cleaner where you suspect you have a vaccuum leak, if the idle smooths out, you've found one. Another way to check for a vaccuum leak is to use a smoke machine typically used to test evap systems for leaks.

 

Ok well as i was changin my pcv valve i heard a hissing sound so im moving hoses around to see if it stops nothing . I look in back of my intake manifold by my brake resevouir i see a lil nipple with out any hose attached to it. I put my finger on it boom the car dies. I think i found my problem. So my question is what hose goes there? Does the hose come from The charcoal canister? Or can i just cap it off?


By the way i converted my auto to stick so i have a ex charcoal canister . Is the em1 charcoal canister different?

 

Is your cruise control plugged in? It might be the vacuum line to the cruise control.

 

Nope it wasnt thank u so
much . Damn it got tucked in with the brake lines and didnt notice it. Could this have cause code po505 to
come up????

 

^Yes. Now reset the ECU to see whether the code no longer returns.

 

Ok plugged the wire up reset ecu drove the car hard and nothing my idle is at around 550 to 800 rpm is that normal? before it was exactly at 1000 rpms

 

The warm idle should be steady at about 700 rpm (no load).

 

Ok cool cause that is where it stays at . Well gonna see what happens and keep any eye on it . Thanks everyone for your help!!!!!!!
