I replaced my intake pipe with 3'' exhaust pipe and now it won't idle.
I need to know what the vacum hose is for that goes into the stock plastic peace from the pass. side of tb.
Call me stupid or whatever but I pluged it.
Is that the problem?

Thanx

Did you take off the afm? There is a line that goes from the oil filler neck to the intake, but I dont remember what the other one is.

 

yea if you take the hose off it will cause it not to idle. i did the same thing. you will need to make a fitting for it on your new pipe.

 

thanks, that is what I needed to know.
now if I can figure out how to connect a fitting.
Hmmmm...

It goes to the BAC.

 

Just put a breather filter on it, it worked for me, dont remember why I did that but oh well, it still worked

 

Yeah, I just needed to connect the vacum hose to the
pipe. It was wierd because the car would idle cold
without it but would die when the temp. raised.
Actually I routed it to the elbow, and I let it get warm
to make sure that was it. Got a pic but it's huge....
