SYMPTOM
Surges D Faulty EGR system (if equipped)
(Variation in D Variable fuel pressure (Clogged fuel filter, faulty
vehicle speed is fuel pressure regulator, etc.)
felt although D Poor performance of MAP sensor
accelerator pedal D Faulty injector(s)
is not operated)
D Faulty ECM (PCM)
Poor gasoline D High idle speed
mileage
D Fuel pressure out of specification or fuel
leakage
D Poor performance of TP sensor, IAT sensor or
ECT sensor
D Faulty EGR system (if equipped)
D Faulty injector(s)
D Faulty ECM (PCM)
Excessive D Engine not at normal operating temperature
hydrocarbon (HC) D Clogged air cleaner
emission D Faulty ignition system
D Vacuum leaks
D Low compression
D Lead contamination of three way catalytic
converter
D Faulty evaporative emission control system
D Fuel pressure out of specification
D Closed loop system (A/F feed back compensa-
tion) fails (vehicle with oxygen sensor only)
– Faulty TP sensor
– Poor performance of ECT sensor or MAP
D Maladjusted CO adjusting resistor (vehicle with-
out oxygen sensor only)
D Poor performance of IAT sensor
D Faulty injector(s)
D Faulty ECM (PCM)
