Buick Regal 2001 3.8L EGR Error code
What could have gone wrong with the intake manifold replacement that would have caused this problem? How do I approach the repair shop to get them to own up to them have making an error in repair?
The other repairs that were done where the valve cover gaskets and oil pan gasket where replaced to correct oil leaks.
Check for a vacuum restriction to the MAP sensor and the electrical connections to the sensor as well as the connection to the egr valve. Inspect harnesses for any damage/corrosion etc.
How does the car run?
The problem has to be diagnosed to dermine where fault may or may not lie. If this is a reputable shop, ask them to troubleshoot the problem. If it is on their end,ask them to cover it, if it isn't, you'll have to.

I had posted before about a reprogram.(I deleted it because it was for a p1404) I didn't want to confuse you...sorry...
I was looking and it doesn't look like that code jives with the EGR valve. Does the car have an air pump for emissions?
