That's interesting because im going throught the same problem. I have a 97 Maxima and the engine light came on. I had it scanned and the code was P1441 which means "Vacuum cut bypass valve or ciruit fault".I dont know what that is. I need help with figuring this out too. try taking out the egr valve and cleaning it really good with break cleaner also change the gasket it's like 3 bucks unhook your battery for 10 minutes to let the computer reset itself after that drive for about 20-30 minutes to let the computer relearn the car then take it to autozone or checkers and use their free code reader to see if it is still reading that code if so change the egr valve all together with. Check the connection between EGR valve tube and the engine. The tube can be easily clogged by carbon deposit from the exhausted gas. At least that is what happened to my 96 maxima. The tube is kind of difficult to reach because it is on the back of the engine, opposite to the firewall.

Can you clean the mass air flow sensor on a 1997 Nissan Maxima?
You can try using commercially available Electrical contact cleaners. These leave no residue and are fast drying. Avoid any contact with the thin wires. If this happens, you better be ready to spend for a brand new one or a surplus. > Leo V. ---- CRC Mass Air Flow cleaner ( I just used it to clean the MAF on my 2002 Maxima SE)

sounds like you need to check your idle air controller or mass air flow meter, need to check you a/f alpha and make sure its around 100 . check your your fuel presure and see if you have pressure during cranking.
What does the 'egr flow malfunction' P0400 and 'O2 Sensor circuit malfunction' P0150 mean on a 1996 Nissan Maxima?
po400 means you have insufficient or excessive exhaust flow within the egr system. The o2 code means it has detected this as well. Chances are both are on because either the egr system is not passing exhaust fumes into the manifolds properly. or the manifold has a leak. You can start by checking the manifold for leaks, cracks, holes, etc. If the manifolds seem tight, try actuating the egr valve. If the egr valve works blow compressed air through the tubes of the egr system and find the leak or clog. Carbon buildup is the number one cause for a clogged egr. Also check the lines make sure they are free of holes and are attached. Dont buy a new o2 sensor until you have fixed the egr code as the egr malfunction will likely set the o2 code again within a few months. hope this helps..
