SUBJECT: Stalls the engine

Ford - 4EAT, Mazda - G4A-EL Stalls the engine in drive
A condition of stalling the engine in drive can be caused by a cracked mass airflow snorkel tube. When the gear selector is moved to a drive range, the engine will tilt toward the rear. When this happens, a snorkel tube that is cracked will allow air to bypass the mass airflow sensor which then stalls the engine.
WARNING
Do not be fooled into thinking that the torque converter clutch is being applied. Always check the snorkel tube before working on the transmission.
