1974 Ford 302 Firing Order – It’s crucial that you know which financial institution (or cylinder Top) is # 1 to help determine a starting place for firing order or perhaps to exchange the right part, like an Oxygen sensing unit, fuel injector or ignition coil.
In the past all of that was needed to determine which lender or cylinder mind is primary was to determine what cylinder mind is positioned the farthest frontward. The one that is considered the most frontward (closest to the leading in the engine) is the number one cylinder and that aspect is banking institution one particular.
But some engines today have cylinder heads that are situated consistently, rendering it tougher to determine which is bank primary and which can be bank second. A few typical good reasons we should know this, for example would be to figure out Oxygen indicator to change when you are looking for B1 S1 (Bank One particular Detector A single), or if perhaps you’re attempting to identify an ignition coil to inspect to get a P0301 (#1 cylinder misfire documented) misfire code.
