Ford 4.6 L Firing Order – It’s vital that you know which lender (or cylinder head) is # 1 to help you figure out a place to start for firing order or just to exchange the right component, as an Oxygen sensing unit, energy injector or ignition coil.
Previously all that was essential to find out which bank or cylinder go is primary was to find out which cylinder brain is positioned the farthest ahead. The one that is regarded as the frontward (nearest the front from the engine) is the main cylinder and therefore part is bank a single.
But a majority of motors right now have cylinder heads that are positioned evenly, which makes it harder to determine which is bank number 1 and which can be lender number 2. A few common good reasons we must know this, as an example would be to decide Oxygen indicator to replace when you are searching for B1 S1 (Lender A single Detector 1), or maybe you’re seeking to track down an ignition coil to examine for any P0301 (#1 cylinder misfire documented) misfire code.
