Before diagnosing symptoms or intermittent faults, perform steps in F - BASIC TESTING article in the ENGINE PERFORMANCE section and TESTS W/CODES - EEC-IV article in the ENGINE PERFORMANCE section. Use this article to diagnose existing driveability problems when there are no trouble codes present.

NOTE: Some driveability problems may have been corrected by manufacturer with a revised Powertrain Control Module (PCM). Check with manufacturer for latest PCM application.

Symptom checks can direct the technician to malfunctioning component(s) for further diagnosis. A symptom should lead to a specific component or system test and/or adjustment.

Use intermittent test procedures to locate driveability problems that DO NOT occur when the vehicle is being tested. These test procedures should also be used if a continuous memory (intermittent) trouble code was present, but no problem was found during KOEO or KOER self test.

NOTE: For specific testing procedures, see I - SYSTEM/COMPONENT TESTS article. For specifications, see one of the following articles in the ENGINE PERFORMANCE section:
