My 03 STR recently threw some well known codes commonly related to vacuum leaks (p0171 p0174). I managed to spray some brake clean and locate the leak on the PCV valve line that runs from the valve past the blower and beneath to somewhere I cannot see. Although the pipe itself is not too pricey, I am not sure where it goes and exactly what else I must remove to replace the pipe. I've already removed the wipers, cowl, intake elbow, blower, and the cross structural bar at the rear of the vehicle engine bay. Before I go any further I attempted to do some research but there isn't a whole lot in the way of detailed info on how to remove that breather pipe on the STR. There are some other brittle pipes surrounding the area I am trying to get to so I thought I'd ask who has any detailed info on how to get this pipe removed or has done this procedure in the past? The pipe in question is number 1 in the diagram I have attached. Although I've been a member of the forum for 4-5 years, I've only read posts and never really posted one myself. Let me state that in case I need to say, do or include something else. Although I will make something happen one way or the other, any and all help is appreciated.

 

I think the manual would be the best bet.

You can get get a copy from here.

Thanks, I'll be sure to go over it.

 

does the hose go back to the throttle body underneath the windshield cowling......i ask because on my 06 str that is the setup...i am not familiar with the 03...if it is the same then I might be able to help you somewhat

 

Yes, the hose definitely goes underneath the throttle body. I just am unsure of whether or not it attaches to throttle body. I have managed to repair the hose itself for the time being and the codes have seemingly went away. I will be taking apart the car this weekend to inspect further. Also still in the process of reading the manual Ducamon kindly suggested.

 

It does connect to the throttle body with the same pinch connector as the other end. It is hard to get to but doable .Take off the windsheild cowling and crossbrace. Take off the intake pipe that goes to the throttle body .There is a bolt on the underside of the oval entry point on it and loosen the clamp on the connecting hose to the throttle body and lift it off. Now you can see what you are dealing with .The hose connection you want is more of a feel it than see it .just follow the hose with your hand...get the right spot to pinch...then pinch and pull the hose....now is a good time to inspect all hoses and connections in that area . Just be careful when fishing around so you do not hear a snap..crackle..pop

 

I appreciate the advice. I think I'll change the throttle body gasket and do a throttle body clean while I have it off. Thanks again for the help.
