ILLUMINATED CHECK ENGINE LIGHT

system.

A malfunctioning secondary air injection pump,
means your emissions system will be allowing too
many hydrocarbons.

WEAK ACCELERATION
A bad secondary air injection pump in your car
will also cause problems for the air-to-fuel
ratio in your internal combustion engine.
12
If this ratio is too lean, then your engine will
not generate enough speed whenever you step on
the gas pedal.
13
ENGINE STALLING
A secondary air injection pump that is wearing
down can cause inconsistent power gaps from the
car engine.
14
If the pump is not replaced, the engine may
continue to stall and will demand expensive
repair work.
15
LOW IDLE
The normal RPM of an idle engine is somewhere
between 600 to 1,000 RPM. 
16
When the RPM drops, you will experience more
vibrations and stalling while driving.

REMEMBER
Always take your car to a certified technician
for receiving adequate repair.
