It may seem weird, but I was checking if I had a dead plug (by unplugging the coil one by one while at idle) and when I tried to check the one under the air inlet, I tryed to disconnect the air inlet from the throttle body and the car stalled!!!! Is it normal that the car die if your disconnected the air inlet from the throttle but you dont disconnect the MAF????? Does the car detect no air flow and stop shooting fuel????
