1999 Ford 4.6 Firing Order – It’s important to know which lender (or cylinder head) is number 1 to aid establish a place to start for firing order or maybe to switch the appropriate component, such as an Oxygen indicator, energy injector or ignition coil.
In the past all that was necessary to find out which bank or cylinder go is # 1 was to find out which cylinder head is positioned the farthest forwards. One that is considered the most frontward (nearest to the top from the engine) is the top cylinder and that area is lender one.
But a majority of engines nowadays have cylinder heads which can be positioned consistently, that makes it harder to find out which is financial institution primary and which can be financial institution second. Several common reasons we need to know this, for example is always to decide Oxygen sensing unit to switch when you would like B1 S1 (Financial institution One particular Sensing unit 1), or maybe you’re trying to track down an ignition coil to inspect for a P0301 (#1 cylinder misfire saved) misfire code.
