1998 Ford F150 Firing Order 5.4 – It’s vital that you know which lender (or cylinder head) is number 1 to help you figure out a starting place for firing order or maybe to exchange the appropriate portion, like an Oxygen sensor, energy injector or ignition coil.
Previously all that was necessary to find out which banking institution or cylinder head is primary was to determine what cylinder head is placed the farthest forward. One which is the most ahead (nearest to the top of your engine) is the main cylinder and therefore side is bank one.
But a majority of motors nowadays have cylinder heads which are placed consistently, which makes it more difficult to find out which is financial institution number 1 and which happens to be lender # 2. A number of typical good reasons we should know this, for instance would be to decide Oxygen sensor to switch when you are looking for B1 S1 (Banking institution One particular Sensor A single), or maybe you’re attempting to identify an ignition coil to inspect to get a P0301 (#1 cylinder misfire recorded) misfire code.
