car started idling rough after i took of my valve cover. so i thought it was my coil packs. really rough idle. but not dying. so i was changing coolant today and i started it up and heard a hissing noise. i felt around and a hose little coupling looked cracked just behind the fuel bar. by the fire wall. it was coming out of a tube coming off the top of the valve cover. i looked closer and the little coupler was broken and the hose was in two peices! the bottom peice was sucking air (hissing noise) i tried ot hook it back up but it was broken. i put my finger in the little hissing hose to cut it off. INSTANT idle smoothed out and quieted down. as soon as i lifted my finger the car started ocughing and sputtering again. i owuld post pics but my phone is messed up. what is this?!?!?

 

auditech....... helpppppp

 

sounds like oyu just need to replace the hose. see if you can pull a part number off the coupler too and hit up a dealership. wish I could be more help but it sounds like you answered your own question

 

i did. but that coupler thing has a little spring in it. so i dont know what this little actuator is..... any help on that

 

nah wish I could. maybe your FPR?

 

it is behind the fuel rail, and it is a vac line, just go to the parts store, for about $1 you get a foot of vac line, then for maybe the same you get small clamps

put both clamps on the vac line, stick one end on the fuel pressure regulator(fpr), the other on the intake mani and tighten the clamps

you are talking about the blue hose in the pic with the arrow pointing to it, right? http://www.audizine.com/forum/showthread.php?t=125055

 

it is not the blue vac line. it is the line and thing just to the right above it. see that black little coupler. thats whats broken. it is separated right there. what is that? CLICK FOR PICTURE

 

probably a check valve....... shouldn't be that much to get a new one

 

thank you much
