04 Ford 5.4 Firing Order – It’s crucial that you know which financial institution (or cylinder head) is primary to help determine a starting place for firing order or maybe to change the right aspect, such as an Oxygen indicator, gas injector or ignition coil.
In past times all that was required to find out which lender or cylinder head is primary was to determine what cylinder brain is placed the farthest forwards. One that is easily the most frontward (nearest the front side from the engine) is the number one cylinder and therefore aspect is lender 1.
But many motors today have cylinder heads that are positioned uniformly, making it more challenging to determine which is bank number one and which can be banking institution number 2. A few popular factors we should know this, for instance would be to decide Oxygen detector to change when you would like B1 S1 (Financial institution One particular Sensor One), or if perhaps you’re looking to find an ignition coil to examine for the P0301 (#1 cylinder misfire saved) misfire code.
