1997 Ford 5.4 Firing Order – It’s important to know which financial institution (or cylinder head) is # 1 to assist determine a place to start for firing order or perhaps to switch the right portion, just like an Oxygen sensor, gasoline injector or ignition coil.
Previously everything was required to find out which bank or cylinder mind is primary was to determine which cylinder go is positioned the farthest frontward. One that is regarded as the forward (nearest to the leading from the engine) is the number one cylinder and that part is bank one particular.
But a majority of engines right now have cylinder heads which can be placed consistently, rendering it tougher to find out which is lender # 1 and which happens to be lender # 2. A few frequent good reasons we should know this, for example would be to decide Oxygen detector to change when you are looking for B1 S1 (Financial institution 1 Sensing unit One), or if perhaps you’re looking to find an ignition coil to inspect to get a P0301 (#1 cylinder misfire recorded) misfire code.
