TomsFocus Posted June 12, 2019 Share Posted June 12, 2019 Has it been diagnosed as an internal engine fault? A missfire can easily be an injector or spark plug! 1 Quote Link to comment Share on other sites More sharing options...
Ennvoqation Posted June 12, 2019 Share Posted June 12, 2019 Why are you replacing the engine? Do you have the DTC codes from the diagnostics? It'll help pin down the fault which could be a simple spark plug/injector fault. Quote Link to comment Share on other sites More sharing options...
Ryan_Tango Posted June 12, 2019 Share Posted June 12, 2019 Check the spark plug gap I'm fairly sure on the 1.6 Ecoboost it should be 0.8mm a lot of NGK spark plugs are appalling for the gap Quote Link to comment Share on other sites More sharing options...
