2004 Honda Accord EX 4 Cyl 2.4L
idle speed adjusted
idle speed is to high.
No adjustment on the engine for the idle speed. If the idle speed is too high - then check these possibilities; first - check for a vauum leak - cracked / damaged vacuum hose (replace as necessary). Then, check the idle air control (IAC) valve. Also, check and clean the MAF sensor - at the air intake hose. Be sure to use an aerosol spray cleaner specific to mass air flow sensors.
