Replace your air Intake boot to repair engine hesitation, stumble, hard starting high and low idle
The air intake boot is used to connect the air filter and mass air flow
sensor to the intake tube and throttle actuator. This rubber like part is
attached using simple hose clamps. Replacing the boot takes about 15 minuets
using everyday tools and can save you enough money by doing it yourself instead
of having it done at a repair shop to have a nice diner with a friend.
The boot is usually made of flexible rubber and over time, vibrations within
the engine coupled with natural degradation of the rubber can cause small cracks
which allow air to be pulled into the engine that was not filtered nor accounted
for. This unmetered air can cause extended crank time, hesitation, poor gas
mileage, high or low engine idle not to mention a check engine light.

Tools and Supplies Needed
Replacement air intake boot
Begin with the car on level ground, engine off, in park with the parking brake set.
Loosen and remove the clamps that secure the boot to the air cleaner housing and the
throttle body. This can be done using a screwdriver or a small socket and ratchet and
turning the clamp screws counterclockwise.
