My Vauxhall Mokka has been idling roughly recently and I'm not sure why. It seems to happen more frequently when the engine is cold and it can be difficult to start the car. What could be causing this issue and how can I fix it?
ReplyThe most common cause of rough idling in vehicles is a faulty or dirty idle air control valve. This valve regulates the amount of air flowing into the engine when the throttle is closed, so if it is dirty or not functioning properly, it can cause rough idling. I suggest checking and cleaning or replacing the idle air control valve to see if that helps resolve the issue.
Another possible cause of rough idling in your Vauxhall Mokka could be a clogged fuel filter. When the filter is dirty or clogged, it can restrict the flow of fuel to the engine and cause it to idle roughly. I recommend checking and replacing the fuel filter if necessary.
