2004 Ford 5.4 Firing Order – It’s important to know which bank (or cylinder head) is number one to help you determine a place to start for firing order or simply to exchange the correct part, just like an Oxygen detector, energy injector or ignition coil.
In the past everything was required to determine which financial institution or cylinder head is # 1 was to determine which cylinder go is situated the farthest ahead. The one that is the most forwards (closest to the leading in the engine) is the number one cylinder which aspect is financial institution one particular.
But some engines these days have cylinder heads which are positioned uniformly, that makes it tougher to find out which is bank number one and which happens to be banking institution number two. Several typical good reasons we need to know this, as an illustration is to establish Oxygen indicator to change when you are searching for B1 S1 (Banking institution 1 Sensor One particular), or if you’re looking to track down an ignition coil to examine for a P0301 (#1 cylinder misfire recorded) misfire code.
