asked by on

On my honda civic 2001 1.6 vtec. My engine management light has come on and the car still drives completely normal only issue I am having is on idle it keeps on wanting to almost cut out and sounds very spluttery... Any idea what can be the cause of this and how can I go about testing what it can be.many thanks

My car has 84000 miles.
My car has a manual transmission.

This may be related to an improper air/fuel mixture which is often times caused by an idle air control valve that is dirty or not working properly. This is a unit that monitors air intake as it is mixed with fuel prior to being injected in the engine. When this is not working properly, this causes an imbalanced air/fuel load to be supplied to the engine causing a rough idle as you describe. I would recommend having an expert from YourMechanic come to your location to test your car for this and repair your idle control valve if necessary.
