Firing Order 2003 Ford Expedition 4.6 – It’s important to know which banking institution (or cylinder Top) is number one to help decide a starting place for firing order or maybe to switch the correct portion, just like an Oxygen sensor, fuel injector or ignition coil.
In past times everything that was required to determine which bank or cylinder mind is primary was to see which cylinder go is located the farthest forwards. The one that is regarded as the frontward (nearest to the top in the engine) is the top cylinder and this area is lender one.
However, many motors right now have cylinder heads that are situated uniformly, that makes it tougher to find out which is bank number one and which is bank number 2. Several popular factors we need to know this, as an example is always to determine Oxygen detector to change when you would like B1 S1 (Banking institution A single Sensor 1), or maybe you’re looking to identify an ignition coil to inspect for the P0301 (#1 cylinder misfire recorded) misfire code.
