2007 Ford Freestar Firing Order – It’s vital that you know which bank (or cylinder Top) is number 1 to help figure out a starting place for firing order or just to replace the appropriate part, like an Oxygen detector, fuel injector or ignition coil.
In the past all that was required to find out which financial institution or cylinder go is # 1 was to see which cylinder brain is situated the farthest forwards. The one which is easily the most frontward (nearest to the top of the engine) is the number one cylinder and that part is financial institution one particular.
But a majority of engines these days have cylinder heads that are positioned consistently, rendering it harder to determine which is bank # 1 and which can be banking institution number two. A few typical reasons we need to know this, as an illustration is always to establish Oxygen detector to replace when you are searching for B1 S1 (Banking institution One Sensor 1), or if you’re seeking to find an ignition coil to examine to get a P0301 (#1 cylinder misfire saved) misfire code.
