Also, the secon d half of the sp ark line is distorted.
This cou l d be a result o f misfiring.

GENERAL INFORMATION
POWER STEERING37-3
GENERAL INFORMATION
M1372000100661
Power steering has been adopted in all vehicles to
make the steering system easier to handle.
FEATURES
•A 4-spoke steering wheel is used. <Invite>
•MOMO leather-wrapped 3-spoke steering wheel
is used. <Intense>
•A steering column has a shock absorbing mecha-
nism and a tilt steering mechanism.
•Integral-type rack and pinion gear with high rigid-
ity and excellent response is used.
•A vane type pump with a fluid flow rate control
system which change steering effort according to
the engine speed is used.
•The separate plastic resin oil reservoir is used to
reduce weight and to make the fluid level check
-
ing easier.
