INSPECTION PROCEDURE 11
When the engine is cold, it stalls at idling. (Die out)
In such cases as the above, the cause is probably thatthe air/fuelmixture isinappropriate
when the engine is cold, or that the intake air volume is insufficient.
Were the battery terminals disconnected?
MUT-II Self-Diag code
Are diagnosis codes displayed?
Does the engine stall right after the accelerator pedal is released?
Is engine-idling stable after the warming-up?
Check the ISC servo for operation sound. (Refer to P.13A-199*.)
Check the injector for operation sound.
