12. Check the CYL1 MISFIRE, CYL2 MISFIRE, CYL3
MISFIRE, CYL4 MISFIRE, CYL5 MISFIRE, and/or
CYL6 MISFIRE in the DATA LIST for 10 minutes
w i t h the HDS.
Does CYL1 MISFIRE, CYL2 MISFIRE, CYL3
MISFIRE, CYL4 MISFIRE, CYL5 MISFIRE,
and/or CYL6 MISFIRE show misfire counts?
Y E S - G o t o step 13.
NO—Intermittent misfire due to poor contact at the
ignition coil connector (no misfire at this time).
Make sure the coil connections are secure. •
13. Determine w h i c h cylinder had the misfire.
Does the misfire occur in the cylinder where the
ignition coil was moved?
YES—Replace the faulty ignition coil (see page
4-22), then g o t o step 55.
NO—Go to step 14.
14. T u r n the ignition switch OFF.
15. Exchange the spark plug f r o m the problem cylinder
w i t h one f r o m another cylinder.
16. Test-drive the vehicle for several minutes in the
range of the recorded freeze data.
17. Check the CYL1 MISFIRE, CYL2 MISFIRE, CYL3
MISFIRE, CYL4 MISFIRE, CYL5 MISFIRE, and/or
CYL6 MISFIRE in the DATA LIST for 10 minutes
w i t h the HDS.
Does CYL1 MISFIRE, CYL2 MISFIRE, CYL3
MISFIRE, CYL4 MISFIRE, CYL5 MISFIRE,
and/or CYL6 MISFIRE show misfire counts?
Y E S — G o t o step 18.
NO—Intermittent misfire due to spark plug f o u l i n g
(no misfire at this time). •
18. Determine w h i c h cylinder had the misfire.
Does the misfire occur in the cylinder where the
spark plug was moved?
YES—Replace the faulty spark plug, then go to step
55.
N O — G o t o step 19.
19. Turn the ignition switch OFF.
20. Exchange the injector f r o m the p r o b l e m cylinder
w i t h one f r o m another cylinder.
2 1 . Start the engine, and let it idle 2 minutes.
22. Test-drive the vehicle for several minutes in the
range of the recorded freeze data.
23. Check the CYL1 MISFIRE, CYL2 MISFIRE, CYL3
MISFIRE, CYL4 MISFIRE, CYL5 MISFIRE, and/or
CYL6 MISFIRE in the DATA LIST for 10 minutes
w i t h the HDS.
Does CYL1 MISFIRE, CYL2 MISFIRE, CYL3
MISFIRE, CYL4 MISFIRE, CYL5 MISFIRE,
and/or CYL6 MISFIRE show misfire counts?
Y E S — G o t o step 24.
NO—Intermittent misfire due to bad contact in the
injector connector (no misfire at this time). Check
for poor connections or loose terminals at the
injector. •
24. Determine w h i c h cylinder had the misfire.
Does the misfire occur in the cylinder where the
injector was exchanged?
YES—Replace the faulty injector (see page 11-211),
then go to step 55.
N O — G o t o step 25.
25. Turn the ignition switch OFF.
26. Disconnect the ignition coil 3P connector f r o m the
problem cylinder.
27. Turn the ignition switch ON (II).
