EGR Hose?

I got a 1997 Chevy Lumina 120,406 miles, runs good, had the car for a few weeks. I got that code on it, the P0401 code. I thought about this; where the
EGR Valve sits, there's a hose on the bottom, with metal coil-like wrapping around it. It leads to the Intake Manifold. Here's my question, that piece of hose is threaded on the Manifold, can you take that off? It might be a dumb question, but I gotta make sure, I'm doing the little stuff, cheap stuff first before I come down to the point of buying a new EGR Valve.

You don't say your reason for taking the EGR tube off. Is the tube threaded onto the manifold? In '95 they were held on by one bolt. Either way, I had to replace mine and the old one came out in pieces, so I wouldn't take it off unless you had to.

I want to take it off so I could clean it out of carbon build-up, and then blow the rest of it with an air gun. I just want to make sure if it's possible for me to do that. It's got those grooves were you could put a combo wrench on it and its very easy to see. But is it okay if I did that?

Anything that was put together can be taken apart. There would have to be serious problems with your car for that relatively large tube to be dirty enough to impair flow of exhaust gas.
All I'm trying to say is that it's more trouble than it's worth, but if you feel the need, by all means, go right ahead.
Now something that's pissing me off is the fact that an EGR tube for a 1997 3.1 is only $34 and I had to pay $160 for a '95 3.4 DOHC tube. F***.

There isn't any huge problems, but it could be later on, just had to get a pro's take on this. But is it really hard to take off even though it's threaded on there? It looks easy, but you probably have to let the engine heat up before you take it off, huh? I'm just trying to take care of this car, I got it for a nice deal of $700, she runs too. I go to a community college for automotive technology, so since I got the summer off, I'll call my instructor and ask him about it. if you can hit me back up about it, I'd appreciate it, but other than that, thanks for the advice.

That's the point of Steve's advice - there isn't likely to be a problem later on. Preventative maintenance is only of value if it's really preventing something.
