1990 Mazda 626 ProblemsMisfires Under Load
Misfires under load (acceleration) can be caused by leaky spark plug boots. When a spark plug boot leaks, it allows the spark to arc, or jump, to the cylinder head. If evidence of arcing can be seen on the inside of the spark plug boot, new spark plug wires will be needed.
If the engine stalls when the automatic transmission is shift into reverse, the intake tube between the mass airflow sensor and throttle body may be split. The damaged intake ducting will need to be replaced.
