I get a code 32 after driving about 100 miles or so, but not all the time. The car doesn't seem to run any worse when the code is thrown, so I don't know if there's anything actually wrong.

I'm guessing this is an EGR problem. I replaced the y-pipe recently, so there shouldn't be a back pressure issue. How do I go about diagnosing the problem? Anyone have a picture of where the EGR valve is, and the easiest way to get to it?

Or is there some other problem I haven't considered yet?

Thanks for everyone's help. :rockon:

My 305 threw that code the day i put headers and an exhaust on it. No matter what I did, it never went away. I have heard that the lack of backpressure can cause this, as was def. true in my case.

I really only mentioned this because you said you changed your Y pipe, is it wider? like a 3" or anything?

No, I replaced it with GM stock. I don't think there's anything special about it, except that they're hard to find anymore.
