INTRODUCTION
Before diagnosing symptoms or intermittent faults, perform
steps in F - BASIC TESTING and G - TESTS W/ CODES articles in the
ENGINE PERFORMANCE Section. Use this article to diagnose driveability
problems that exist when a hard fault code is NOT found, or on vehicle
NOT equipped with a self-diagnostic system.
NOTE: Computer control unit has been revised to correct certain
driveability problems. Check with manufacturer for latest
computer application.
Symptom checks are intended to direct technician to
malfunctioning component(s) so further diagnosis may be performed. A
symptom should lead to specific component or system testing, or an
adjustment specification.
Use intermittent test procedures to locate driveability
problems that DO NOT occur when vehicle is being tested. These test
procedures should also be used if a soft (intermittent) trouble code
was present, but no problem was found during self-diagnostic testing.
NOTE: For specific testing procedures, see I - SYS/COMP TESTS
article in the ENGINE PERFORMANCE Section. For
specifications, see C - SPECIFICATIONS or D - ADJUSTMENTS
article in the ENGINE PERFORMANCE Section.
SYMPTOMS
SYMPTOM DIAGNOSIS
Symptom checks cannot be used unless problem occurs while
vehicle is being tested. Symptoms available for diagnosis include the
following:
* Difficult to start/no start (cranks okay)
* Rough or unstable idle
* Engine hesitates or poor acceleration
* Engine surges
* Detonation or knocking
* Poor fuel mileage
SYMPTOMS (PFI)
DIFFICULT TO START/NO START (CRANKS OKAY)
* Check idle speed control servo (if applicable).
* Check stepper motor (if applicable).
* Check ignition switch.
* Check TDC sensor.
* Check crank angle sensor.
* Check inhibitor switch (A/T).
