1991 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.

Spark plugs are leaking water well 2 are is my engine a rebuild?
This happened after adding the same brand fuel and may have been when the new fuel entered the engine.
How do I determine the battery size and what is the best place to get a battery in the Northern Virginia or nearby areas of MD or DC. I just need the battery, not changing the cables. Thanks!
