ENGINE POWER DROPS WHEN CLUTCHED DOWN

1994 Honda Accord

Engine Performance problem
1994 Honda Accord 4 cyl Front Wheel Drive Manual 197000 miles

I drive a 1994 Honda accord, recently its takes like two to three attempts to start my car in the morning and it seems to idle well when started, but when drivien into the highway I observe that my engine rpm suddenly drops below the 900-1000 stable value when ever I clutch down to move either to a lower or higher gear, this experience is worsened if I have the car A/C on while driving. Please what could be the likely cause.

Hi adewumi,

The recommended idling speed is 720 to 820 and 900 is already too high. You have aproblem with the idling circuit and you need to
1. Clean the throttle body.
2. Clean EACV (Electronic Air Control Valve.
3. Check the valve clearances. If insufficient clearance, it wll tend to drop before going back up.
