B16a1 EF8

I'm throwing 3 Codes, MAP sensor, KNOCK sensor & Primary Oxygen Sensor - Heater.

The knock sensor needs to be wired up again,

I'm confused about the O2 Sensor.. when it says "heater" in the codes, does that mean it is the o2 sensors on the header?

& the MAP sensor i'm pretty sure the vac lines we're re-arranged..

I have a pdf of the EF8 JDM B16a Owners Manual, I've printed off the vacuum line diagram but i'm still confused on the whole situation, every diagram seems to be a little different.

Heres a couple pictures, PLEASE let me know if you see anything wrong such as the vac lines being in the wrong place etc etc.









Theres also a locking tab/connector with a connector out of place? I have no idea what it is used for, wondering if anyone knows what this is? (on firewall)





My o2 Sensors on the header have been replaced - and are in the correct order i beleive..
Green - on the right side of the header where the timing belt is
Cream Colored - on the left side (standing in front) closest to where the battery would be



Could it be that the connector pin(s) in the locking tabs for the o2 sensors are bent and have no connectivity? (Running Rich)

 

Did you spray some startup/carb fluid around the intake and around the vacuum lines yet?

 

this is what i used and i have no codes or problems, as of the o2 sensors does your car feel sluggish at bottom end just cruising?

 

Sea-foam in vacuum lines yes, throttle body cleaner aswell

before my car did seem sluggish bottom end,

but now my vtec is working, car seems to be a hell of alot better on gas and rips.

except it has a high idle, 2000 rpms~, at lowest 1500 rpms..

any ideas?

 

Would the fact that the RED vacuum line (charcoal cannister) was in the position in the map sensors vacuum line position cause bad gas mileage? running rich? I'm going to check my codes again and update.

thanks!

 

if it runs a little rich and at like slight throttle it hesitates a little your o2 sensors are backwards your can change them at the ecu, your high idle could be a vacuum leak or hooked in the wrong place...

 

okay thanks, it is running alot better, along with the iacv adjusted etc.

thanks again
