INSPECTION PROCEDURE 8

Unstable idling (Rough idling, hunting)

Probable cause

In cases as the above, the cause is probably that the ignition system, air/fuel mixture,

idle speed control (ISC) or compression pressure is defective.

Because the range of possible causes is broad, inspection is narrowed down to simple

items.

Malfunction of the ignition system

Malfunction of air-fuel ratio control system

Malfunction of the ISC system

Malfunction of the purge control solenoid valve system

Malfunction of the EGR solenoid valve system

Poor compression

Drawing air into exhaust system
