Hi there,

I have a 2001 honda civic standard transmission. Today the engine started revving without me touching the gas. Does anyone know what this might be?

Thanks,

. Clean Idle Air Control Valve (IACV):

While you are at it, clean the throttle plate, ports, and throttle body.

. Set curb idle to specs:

. Check/replace the Engine Coolant Temperature (ECT) Sensor, if the problem persists.

Take the iac off and put something thin and plactic to block it off put the iac back on it fixed mine
