To all that can help~
I have been getting the code for EGR Valv insuficient flow, so I replace my EGR Valve. The CEL stays off for 5 days and is now back. What else could be the problem! I am going to Windsor next week, and I don want any car problems at all!
Thanks in Advance

Insufficient flow is usually caused by EGR passages in the intake manifold being plugged up. The most common place is right behid the throttle body. If you remove the throttle body, the passage will be exposed and you should be able to see what is needed to clean it.

Besides the above, it could also be a bad EVR (EGR Voltage Regulator). I am going to Windsor next week, and I don want any car problems at all! I don't think that you need to worry too much about the P401. It basically means that you are spewing emissions into our atmosphere at a higher rate than normal. Get it fixed at your convenience.

I don't think that you need to worry too much about the P401. It basically means that you are spewing emissions into our atmosphere at a higher rate than normal. Get it fixed at your convenience. I believe EVR means EGR Vacuum Regulator. It's really a solenoid valve (open or closed) that regulates vacuum to EGR valve. While I would generally agree with the above statement, in view of your destination I would say get it fixed sooner rather than later.  p.s. Seriously, I think first step should be reset PCM and see if or when CEL next appears. p.p.s. Why don't you delete 6:04pm post and clean up the board.
