Symptom Diagnosis

Symptom checks cannot be used properly unless the problem occurs while the vehicle is being tested. To reduce diagnostic time, ensure basic diagnostic procedures in BASIC TESTING - 2.7L article and self-diagnostics in TESTS W/CODES - 2.7L article were performed before diagnosing a symptom. Symptoms available for diagnosis include:

• Engine Cranking Or Starting Problems
• Engine Idling Problems
• Engine Driveability Problems
• Engine Stalling Problems
