1. Check the fuel pressure (see FUEL PRESSURE TEST ).

Is the fuel pressure OK?

YES -Go to step 2.

NO -



If the pressure is too high, replace the fuel pressure regulator (see FUEL PRESSURE
REGULATOR REPLACEMENT ), then go to step 7.



If the pressure is too low, check the fuel pump, the fuel feed pipe, and the fuel filter. If they are OK,
replace the fuel pressure regulator (see FUEL PRESSURE REGULATOR REPLACEMENT ),
then go to step 7.

2. Check for vacuum leaks at these parts:



PCV valve



PCV hose



EVAP canister purge valve



Throttle body



Intake manifold



Brake booster



Brake booster hose



Intake air duct

Are the parts OK?

YES -Go to step 3.

NO -Repair or replace parts with leaks, then go to step 7.

3. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator

fan comes on, then let it idle.

4. Check for these conditions:



Engine coolant temperature (ECT SENSOR 1) above 158°F (70°C)



M/T in neutral (A/T in Park or neutral)



All electrical loads off

5. Monitor the ENGINE SPEED in the DATA LIST with the HDS, and hold the engine speed at 2,500 rpm.

Once the engine speed is met, hold the accelerator pedal steady for more than 10 seconds.

Did the engine speed vary more than 100 rpm from 2,500 rpm?

YES -Repeat step 5.

NO -Go to step 6.

6. While holding the engine speed at 2,500 rpm, check the MAF SENSOR in the DATA LIST with the

HDS.

Is there about 6.4-9.2 gm/s?

YES -Check the engine valve clearances and adjust if necessary (see VALVE CLEARANCE
ADJUSTMENT ). If the valve clearances are OK, replace the injectors (see INJECTOR
REPLACEMENT ), then go to step 7.

NO -Replace the MAF sensor/IAT sensor (see MAP SENSOR REPLACEMENT ), then go to step 7.

7. Turn the ignition switch ON (II).

8. Reset the ECM/PCM with the HDS.

9. Do the ECM/PCM idle learn procedure (see ECM/PCM IDLE LEARN PROCEDURE ).

10. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator

fan comes on, then let it idle.

11. Check for these conditions:



Engine coolant temperature (ECT SENSOR 1) above 158 T (70°C)



M/T in neutral (A/T in Park or neutral)



All electrical loads off

12. Check for Temporary DTCs or DTCs with the HDS.

Is DTC P0171 or P0172 indicated?

YES -Go to step 1.

NO -Troubleshooting is complete. If any other Temporary DTCs or DTCs are indicated, go to the
INDICATED DTCS TROUBLESHOOTING.

DTC P0300: RANDOM MISFIRE AND ANY COMBINATION OF THE FOLLOWING; DTC P0301:
NO. 1 CYLINDER MISFIRE DETECTED; DTC P0302: NO. 2 CYLINDER MISFIRE DETECTED;
DTC P0303: NO. 3 CYLINDER MISFIRE DETECTED; DTC P0304: NO. 4 CYLINDER MISFIRE
DETECTED

NOTE:

DTC P0171 and/or P0172 may take up to 80 minutes of test driving to set.
Using the HDS, monitor the air fuel feed back average (AF FB AVE). If the
AF FB AVE stays within 0.82-1.18, there is no problem at this time.

1. Turn the ignition switch ON (II).

2. Clear the DTC with the HDS.

3. Start the engine, and let it idle without load (in Park or neutral).

4. Monitor the OBD STATUS for DTC P0301, P0302, P0303, or P0304 in the DTCs MENU with the HDS.

Does the screen indicate FAILED?

NOTE:



Before you troubleshoot, record all freeze data and any on-board
snapshot, and review the general troubleshooting information (see
GENERAL TROUBLESHOOTING INFORMATION ).



If the misfire is frequent enough to trigger detection of increased
emissions during two consecutive driving cycles, the MIL will come on,
and DTC P0300 (and some of the combination of P0301 through P0304) will
be stored.



If the misfire is frequent enough to damage the catalyst, the MIL will flash
whenever the misfire occurs, and DTC P0300 (and some of the
combination of P0301 through P0304) will be stored. When the misfire
stops, the MIL will remain on.



If any of the DTCs listed below are indicated at the same time as the
random misfire DTCs, troubleshoot those DTCs first, then recheck for
these random misfire DTCs:

YES -Go to step 9.

NO -If the screen indicates PASSED, go to step 5. If the screen indicates EXECUTING, keep driving
until a result comes on. If the screen indicates OUT OF CONDITION, wait several minutes, then recheck.

5. Check the CYL1 MISFIRE, CYL2 MISFIRE, CYL3 MISFIRE, and/or CYL4 MISFIRE in the DATA

LIST for 10 minutes with the HDS.

Does (he CYL1 MISFIRE, CYL2 MISFIRE, CYL3 MISFIRE, and/or CYL4 MISFIRE show misfire counts?

YES -Go to step 9.

NO -Go to step 6.

6. Test-drive the vehicle several minutes in the range of these recorded freeze data parameters:



ENGINE SPEED



VSS



REL TP SENSOR



CLV (calculated load value)



APP SENSOR

7. Monitor the OBD STATUS for DTC P0301, P0302, P0303, or P0304 in the DTCs MENU with the HDS.

Does the screen indicate FAILED?

YES -Go to step 9.

NO -If the screen indicates PASSED, go to step 8. If the screen indicates EXECUTING, keep driving
until a result comes on. If the screen indicates OUT OF CONDITION, go to step 6 and recheck.

8. Check the CYL1 MISFIRE, CYL2 MISFIRE, CYL3 MISFIRE, and/or CYL4 MISFIRE in the DATA

LIST for 10 minutes with the HDS.

Does the CYL1 MISFIRE, CYL2 MISFIRE, CYL3 MISFIRE, and/or CYL4 MISFIRE show misfire counts?
