here's what happened in short:

my car was doing very good, i went to the car wash to meet a friend (didnt wash my car) i opened my agency power BOV cover thing to let him hear the sound (was closed before) after that my AFR went crazy, reading 17+ when idleing and 12.5~14.5 when at full throttle,

so i started snooping around but couldnt find any thing.
but just to be sure, is this harness supposed to be unplugged (the gray one)??




please help!!!

 

Mines unplugged!

 

^^ thats good to know

 

so your question is afrs or the plug? lol

 

no i just suspected the plug, but now that its not it, WTH is happening, why is it so lean ??

 

so you Set your BOV to VTA and then you had these AFR's? If this is the case try unpluging you negative battery cable for 10 mins or so to reset you ECU and see what happens.

 

will do

 

Are you throwing a code now? Mine threw a "too lean" code when my o2 housing cracked.

My AFRs were 18-19 at idle and basically normal on throttle though.

 

Check your Fuel Pressure regulator line, it probably popped off, I've seen that happen on two X's so far (one was mine).

Either that or your BOV spring is too soft and it is pulling in un metered air since you switched it to vta. Unless you did something silly like had it set to recirc and just pulled the end out of the intake pipe, in which case you are sucking in a ton of un metered air.

 

exactly whats happening to me right now

i will see what i can do

 

I zip tied mine last night.

 

thanx fellas all fixed
turned out to be a poped out hose on the throttle body...
zip tied the hell outta of it

 

At 30+psi, its definately a requirement.

 

I blew that line off my VIII with a TME 16G at 25psi on race gas back in 2005. Sucked, cracked a piston. When I went to a 30R and 31psi, everything was zip tied.

Live and learn.
