This GM's definition of this code:
P1404 - Exhaust Gas Recirculation (EGR) Closed Position Performance
The most common reasons are either the EGR valve position sensor is defective, or the EGR valve is not fully closed due to carbon.

I would try to clean out the egr valve , check for leaks at the evap canister, check the evap canister soleniod , and lastly change out the cat convertor, The cat convertor is most likely under the federal emmission warranty of 8 yrs,.80000 miles. You can take the vehicle in to have checked by local dealer or call gm customer service to check the warranty on the cat. convertor by giving them your vehicle number.

REMOVE EGR VALVE CLEAN OUT THE CARBON INSIDE THE EGR VALVE PORT HOLE IN THE INTAKE MANIFOLD WHERE EGR VALVE SITS.CAREFULLY USE A PIECE OF CLOTHES RACK OR A TINY SCREW DRIVER CLEAN CARBON OUT ROUND HOLE.USE A SHOP VAC TO VACUUM UP THE DEBRIS TO KEEP FROM GETTING INSIDE INTAKE.DONT USE SHOP VAC IF YOU HAVE ANY FUEL LEAKS OR SMELL GAS FUMES UNDER THE HOOD.

Testimonial: "thanks will give it a try."
My 2000 Bonneville did the exact same thing. It's the mass flow air sensor I'm almost 100% sure this is what your problem is.

My first thought would be the converter considering the codes....which will cause the sensors/heaters and other components to fail or read as being bad... I would call a dealer and make sure there are no recalls on the emissions systems and anything to do with the vehicle..
Also it would be worth your while to scan it with a TECH 2 scanner......You may have one I dont know......But I worked for Buick/Pontiac/GMC for 5 years and TECH 2 was a life saver...
It will tell you everything !! If it is running fine though I would just change the oxygen sensor,
clear the codes,test drive it then check it again.....But if you have no problem with it and hooked it to an emissions analyzer and it showed ok I wouldnt worry....
