Question about 1995 Nissan Maxima
Hi, the common denominator here may be the wiring. With the car behaving poorly and the code indicating the MAF sensor, I would guess a bad wire or two involved here. If you have a multimeter, you can run the tests below to verify that the data is bad. The MAF signal at pin 1 should be the white wire--I guess. Then the ground would be the black wire. Do check for the battery voltage on the red wire. For the IAT sensor, the reference voltage might be 5 volts on the black wire. The white wire should have a somewhat lower voltage with the (key on). If you are not seeing these voltages, trace the wires back to find the problem. The ECU in under the glove box. If the signals look good at the sensors, you may need to check them at the ECU. You can also back-probe the ECU connector,. since you'll want it connected with the key on to check the signals. Just match the wire colors and pin numbers to make sure you are checking the right signal. Please let me know if you have questions, and thanks for using FixYa.

I see two potential problems occuring.
1) It sounds like your timing isn't set correctly and would need to be re-timed
2) Your mass air flow was put in backwards and simply needs to be turned around.
I hope this helps.
