2004 Ford Expedition 5.4 Firing Order – It’s crucial that you know which lender (or cylinder head) is number one to aid establish a starting point for firing order or simply to switch the right portion, such as an Oxygen sensor, gasoline injector or ignition coil.
In the past all of that was required to find out which banking institution or cylinder mind is # 1 was to find out which cylinder head is placed the farthest frontward. The one which is considered the most forwards (nearest to the front from the engine) is the best cylinder and therefore side is bank 1.
However, many engines today have cylinder heads which can be situated consistently, rendering it harder to find out which is banking institution number one and which happens to be lender number 2. A few typical motives we must know this, as an example would be to figure out Oxygen sensing unit to switch when you are searching for B1 S1 (Lender One Sensing unit 1), or if perhaps you’re trying to find an ignition coil to inspect for a P0301 (#1 cylinder misfire documented) misfire code.
