Firing Order 2004 Ford F150 5.4 – It’s important to know which bank (or cylinder Top) is primary to aid establish a place to start for firing order or maybe to replace the proper part, like an Oxygen sensing unit, energy injector or ignition coil.
Previously all of that was essential to find out which bank or cylinder head is number one was to see which cylinder brain is located the farthest forwards. One that is considered the most forward (closest to the top of your engine) is the main cylinder and therefore side is bank one particular.
But some engines today have cylinder heads which are located equally, making it harder to find out which is financial institution number one and which is banking institution second. A number of common good reasons we should know this, as an example is always to figure out Oxygen sensor to change when you would like B1 S1 (Lender 1 Sensor One particular), or if you’re trying to track down an ignition coil to inspect to get a P0301 (#1 cylinder misfire documented) misfire code.
