IDLE SPEED Engine must be at normal operating temperature. Adjust idle speed with air cleaner installed, all air intake system hoses connected, all vacuum lines and emission control wiring connected, air conditioning off, electric cooling fan disconnected and transaxle in Neutral. Ensure some slack exists in accelerator cable and all accessories are off. On Spectrum, disconnect and plug the following: Distributor vacuum line, canister purge line, EGR vacuum line, and ITC valve vacuum line. Connect timing light and tachometer to engine. Ensure valve adjustment and ignition timing are set to specifications. Set idle speed to specifications by turning idle speed adjusting screw. Set it at 1K rpm
