2004 Ford Mustang 3.9 L Firing Order – It’s crucial that you know which financial institution (or cylinder Top) is number one to help determine a starting point for firing order or perhaps to exchange the proper component, such as an Oxygen detector, energy injector or ignition coil.
In past times everything was needed to determine which lender or cylinder mind is # 1 was to determine what cylinder brain is situated the farthest forward. One which is regarded as the forwards (closest to the leading from the engine) is the top cylinder and that aspect is bank a single.
But some motors today have cylinder heads which can be placed consistently, which makes it more challenging to determine which is banking institution primary and which happens to be banking institution number 2. Several frequent reasons we must know this, for instance is usually to determine Oxygen sensing unit to replace when you are interested in B1 S1 (Financial institution One particular Detector 1), or maybe if you’re looking to track down an ignition coil to inspect for any P0301 (#1 cylinder misfire saved) misfire code.
