Idle Speed: Notes
- Ensure coolant temperature is 176-203°F (80-95°C). Turn all accessories off. DO NOT check curb idle speed while cooling fan is operating. On vehicles equipped with power steering, ensure front wheels are in straight-ahead position.
- Connect scan tool to DLC located at lower crash pad, below steering column. Operate engine at curb idle speed and then operate engine for at least 5 seconds at 2000-3000 RPM.
- Run engine at idle for 2 minutes. Check idle RPM. See the IDLE SPEED SPECIFICATIONS
table. If RPM is not within specification, go to next step.NOTE: DO NOT adjust throttle valve Speed Adjusting Screw (SAS). SAS is pre-adjusted at factory. Idle is controlled by Idle Speed Control (ISC) motor.
- Ensure timing is set to specification. Check throttle body for cracks, restriction in vacuum port or passages, or binding accelerator cable. Also, check input and output value of relevant sensors. See THROTTLE POSITION (TP) SENSOR .
