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.
