2003 Ford 4.6 Firing Order – It’s essential to know which bank (or cylinder head) is number one to help you determine a place to start for firing order or simply to replace the appropriate portion, like an Oxygen sensor, energy injector or ignition coil.
In past times everything was necessary to find out which banking institution or cylinder go is primary was to see which cylinder brain is positioned the farthest frontward. One which is easily the most ahead (closest to the front side from the engine) is the number one cylinder and this aspect is lender a single.
But a majority of motors nowadays have cylinder heads that are positioned equally, that makes it tougher to find out which is lender number 1 and that is bank # 2. Several common motives we need to know this, for example would be to determine Oxygen indicator to exchange when you are looking for B1 S1 (Financial institution One particular Sensor A single), or if perhaps you’re seeking to track down an ignition coil to inspect to get a P0301 (#1 cylinder misfire documented) misfire code.
