CARBON REMOVAL PROCEDURE
WARNING:
PLEASE USE CAUTION WHEN USING ENGINE CLEANER.
WEAR EYE PROTECTION AND GLOVES WHEN HANDLING.
ENGINE CLEANER IS FLAMMABLE.
NOTE:
It IS NECESSARY to perform CARBON REMOVAL when REPAIR PROCEDURE "B" is performed. If vehicle started when performing REPAIR PROCEDURE "A", it IS NOT NECESSARY to perform CARBON REMOVAL.
An assistant may be necessary while performing this procedure.
Approximately half a can of engine cleaner will be used per vehicle during this repair.
1. Cleaner kit comes with engine cleaner (A) and engine cleaner spray hose (B).
NOTE:
Engine cleaner spray hose (B) is not used for this procedure and can be discarded.
The can of engine cleaner (A) will have a red plastic spray tube attached to it. This red spray tube will be used for this procedure.

2. Cut a piece of electrical tape 2" (5cm) long and wrap around the end of the red spray tube.

3. Cut a length of 1/8" inside diameter (ID) vacuum hose (obtained locally) to 27" (70cm). Insert tape wrapped end of red spray tube into vacuum hose and use a tie wrap to hold in place

4. Disconnect Eccentric Shaft Position Sensor (ESPS) B1-27 connector.
NOTE:
This will cut fuel injection and spark while performing the procedure.

5. Remove the front vacuum plug or PCV vacuum hose from the passenger side of the lower intake manifold

NOTE:
2006 model year and later vehicles have PCV vacuum hoses attached to these ports for the PCV system. Disconnect these hoses from the lower intake manifold ports one at a time when performing this procedure. These hoses do not need to be plugged once disconnected.
CAUTION:
DO NOT attempt to service both vacuum ports at the same time. Perform procedure for front port, then perform procedure for rear port.
6. Attach the vacuum hose end into front port nipple.
NOTE:
Ensure the vacuum hose is securely connected to the nipples to prevent the hose from becoming detached while spraying engine cleaner.

7. Attach the red spray hose end into the spray nozzle of the engine cleaner. Use care not to push down on the nozzle when inserting to prevent the can from spray cleaner.

8. Have an assistant crank the engine. While cranking the engine, simultaneously depress the spray nozzle of the engine cleaner for a duration of 10 seconds. After 10 seconds, stop spraying and cranking at the same time. DO NOT depress accelerator pedal while cranking.
9. Wait a minimum of 30 seconds and repeat STEP 8 for the same port.
10. Remove the vacuum hose from the lower intake manifold nipple.
11. Reconnect PCV vacuum hose or install vacuum plug to front nipple.
12. Repeat STEPS 5-11 for rear nipple.
13. Allow the engine cleaner to soak for at least 1 hour before starting engine.
14. Connect ESPS connector B1-27.
15. Attempt to start engine without depressing accelerator pedal.
16. Keep engine running between 1500-2000 RPM until engine speed has stabilized. Maintain this engine speed until all smoke has dissipated and / or engine has come to full operating temperature.
CAUTION:
Do not race the engine during warm-up, this may cause catalyst damage.
17. Rev engine from idle speed up to 6,000 RPM, then release throttle immediately until RPM returns to idle speed.
18. Repeat 20 times with vehicle in Park (AT) or neutral (MT).
19. Connect M-MDS to vehicle and ID vehicle.
20. Using DATALOGGER, select MOP POS#
21. Perform METERING OIL PUMP (MOP) simulation test.
22. Using DATALOGGER, select MOP POS# and RPM.
