2004 Ford Explorer Firing Order – It’s crucial that you know which financial institution (or cylinder Top) is # 1 to help you decide a beginning point for firing order or perhaps to change the right aspect, like an Oxygen sensor, energy injector or ignition coil.
In past times everything was necessary to determine which financial institution or cylinder brain is primary was to determine what cylinder mind is positioned the farthest forward. One which is considered the most forward (closest to the front of the engine) is the main cylinder and that aspect is bank a single.
However, many motors nowadays have cylinder heads which can be located consistently, which makes it tougher to find out which is banking institution number 1 and which is bank # 2. A number of frequent good reasons we should know this, for instance is to establish Oxygen sensor to switch when you would like B1 S1 (Lender 1 Indicator A single), or if you’re seeking to identify an ignition coil to inspect for any P0301 (#1 cylinder misfire saved) misfire code.
