greggp Posted June 9, 2011 Share Posted June 9, 2011 recently when starting up my fiesta (1.4 zetec petrol) 53 plate with 80k miles done it seems to rev a lot higher than it use but seems to settle back to normal after a short time. It idles okay when warm and only seems rev a lot higher on startup not sure if this could be ECU relataed or anything to worry about?

Did you manage to find the cause? Quote Link to comment Share on other sites More sharing options...
