Test Step 12

12) Check Faults Which Affect Idle Speed Check the following mechanical items for faults:

Throttle linkage and/or cruise control linkage for sticking or binding
Throttle body for contamination
Vacuum hoses (check emission decal)
Check for leaks around ISC solenoid (gaskets, etc.)

If all of the above items are okay, remove ISC solenoid and inspect for contamination. Service as necessary and rerun QUICK TEST. If code or symptom is still present, replace ISC. If any of the above items are faulty, service as needed. Remove breakout box. Reconnect components. Rerun QUICK TEST.

NOTE: There is a break in the step numbering sequence at this point, skipping from step 12) to step 15). Break is due to previous chart references to these testing procedures. No test procedures have been omitted.
