Hi I'm new and have a p0171 code, can you help?



On a NA 3800, are there any common vac lines to worry about? Wife won't let me go poking around because I usually break something :/ or else I'd be dissecting as we speak.
 
There are several that you need to be concerned with. You should have somewhere a sticker with the diagram of the vacuum routing. This is just one of the many places a vacuum leak can be coming from but its definitely a good place to start.

Any luck clearing P0171 Crysalis ? FalconJohn , I am still chasing. Cleared the p0441,previous owner had the hoses routed wrong. Just checked the pcv valve and noticed no o-rings ? Does the 3800 SC PCV have o-rings ?
 


No joy here mine comes and goes but no joy. Should be one O ring on PCV. Look inside the hole it tends to stay in there when you pull the PCV out.

Yep I found mine. Did a smoke test and found a hose completely unplugged. I'm a lucky one I guess.
 
wish mine was that easy, no visible vacuum leaks from the smoke test. I'm really think it's payback for something I did in another life. Too bad I can't remember what!
 
Will find o-ring this weekend. List of weekend checks in my fight with p0171 :
o-ring, battery cables check,egr tube for cracks,
 


That's why you are my friend!!!! :th_winking: I'm done until spring I think, gonna do my other eye in three weeks and then I think it's gonna snow! I promise you I will change the other cable in March. It still goes out every week or two for a day or so, gotta believe it is electric at this point.
 
If you have 160K on your car and it's completely stock you might need gaskets too. Have you had it smoke tested? I also had a leaky SC gasket and TB.
 
That gasket didn't fix ya though John. You know..that negative cable is still loose from when you put the positive one to it. Why let it corrode over the winter...you know you want to change it out.
