I have a 1996 explorer that 1 or 2 times a month, the check engine light comes on. When I read the code I get a P0401, indicating excessive EGR flow like the EGR valve is stuck open. I have a new EGR valve, tube and sensors. And I still get the P0401. Any ideas? I have already changed the vaccume and rubber lines connected to the accociated items. Thanks in advance. It is possible the new EGR has a sticking problem, but I thought I'd ask here anyway thanks
