SECTION: 303

Engine Misfire / Injector Clogging / Air Intake System Cleaning

AFFECTED VEHICLE RANGE:

CONDITION SUMMARY:

Situation:

The engine may exhibit a misfire, poor fuel economy, hard starting, and I or a rough idle condition. The engine Malfunction Indicator Lamp (MIL)

may also be illuminated with misfire Diagnostic Trouble Codes (DTC) P0301 through P0308 and P0316, depending on the affected cylinder(s),

stored in the Engine control module (ECM). This may be caused by poor fuel quality or fuel contamination, leading to clogged fuel injectors and

restricting the fuel injector flow rate.

NOTE:

After basic testing has been carried out (checking coil and harness for damage, checking injector harness connections, spark plug fouling, correct

fuel pressure, no fuel filter blockages etc) and if no fault can be found, then using the BG special tool (BG 9210 [or BG 9290] VIA(TM) Vehicle

Injection Apparatus) and cleaner (BG Air Intake System Cleaner 206 and BG 44K(R) Power Enhancer(R) 208) please carry out a fuel induction

system cleaning.

Action:

In the event of a customer concern of the above, refer to the Repair Procedure outlined below to clean the fuel injection system using a pressure

cleaner.
