Did you read the link above? Your problem is electrical - not mechanical. (BTW - The only way your lid would be an issue is if a dead animal, etc. were in there and blocking airflow.) If you changed the MAF, then you have a cut or unplugged wire somewhere.
You should start measuring the voltage at the sensor plug and then work your way back through the circuit until you find the break.

Three wires:
Yellow - Sensor Signal
Black/White - Ground
Pink - Ignition Feed
With the ignition on but the engine off, you should see 5V between the Yellow and Black/White wire.
The factory manual has a very long procedure for testing the circuit, which involves testing the PCM and electrical frequency from the sensor, etc.
The manual also says that the code can be set by:
- Broken wires
- Engine vacuum leaks
- PCV leaks
- An incorrect PCV valve
- Missing engine oil fill cap
- Unseated engine oil dipstick

Verdad Gallardo Not sure - maybe the opening in the crankcase throws off the MAP sensor and the code is thrown when the MAP and MAF are out of balance.
Do you have your dipstick in? When was the last time you changed your PCV?

I just did headers on my car and when i put the dipstick back in the bolt on the head wasnt going in all the way.... I bought the car 3 weeks ago so idk when the PCV was last changed
