Got rid of codes, now I have new ones!

Thanks alot for helping me with the last ones, I temp fixed it by making a new ground wire from my TPS sensor. Car is no longer slow but when I am driving and put the clutch in and let off the gas to stop the car stalls. Sometimes it saves itself and then stalls but its a real pain in the arse. CE light comes on everyonce and a while and sometimes it will go back off. Pulled the codes and got this.

Key on engine off:

157- MAF below minimum voltage

332- Insuffecient EGR sensor valve opening detected

Key on engine on:

172 Heated 02 sensor indicates lean condition right side

136- Heat O2 sensor indicates lean condion, left side

The o2 sensors reading lean might be cause of some bad wiring under there, I used crimps instead of soldering the extentions so ill have to fix that. The EGR im just gonna delete cause there is so many things that can go wrong with that thing so I figure if its gone I wont have to worry about it. What can I do about code 332? Think my reasoning is right for the 02 sensors and the EGR? Could that be whats causeing my car to stall?
