1990 Mazda 626 Problems
Misfires 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.
Knocking from suspension on rough roads due to worn or loose sway bar links
Stalls When Shifting Into Gear
If the engine stalls when shifting into gear, the igniter should be inspected.
Surging When Driving in Forward Gears
If the engine surges while being driven in the forward gears, the intake tube between the mass airflow sensor and throttle body may be split. The damaged intake ducting will need to be replaced.
Stalls When Automatic Transmission is Shift Into Reverse
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.
Engine Stalls when Coming to a Stop
If the engine stalls when coming to a stop, check the automatic transmission fluid (ATF) level. Low ATF fluid level can cause the torque converter lock-up to stay on, stalling the engine.
