Re: EF Futura Sudden poor idle when cold
I am having bad dejavu!!!!!!
I have had that problem since a second hand engine had gone in my car.I changed fuel filter ,replaced coolant sensor ,map sensor,ego sensor,replaced ics,replace tps,new battery,cleaned throttle body,cleaned battery terminals,cleaned ecu relay...clean injectors...
I ended up getting it leak tested at ford and it confirmed 2- 3 cylinder had a leak but was not losing coolant.Forget pressure testing of cooling system,mine showed nothing wrong.
I ended up with another engine yesterday under warranty and this morning it started first go without bad idle.
Do yourself a favour ..get a leakdown test,it will show the condition of the engine..
