03 Ford F150 5.4 Firing Order – It’s essential to know which lender (or cylinder head) is number 1 to aid figure out a starting place for firing order or perhaps to replace the proper part, as an Oxygen sensing unit, energy injector or ignition coil.
Before everything that was essential to determine which lender or cylinder go is # 1 was to see which cylinder head is placed the farthest frontward. One that is the most frontward (nearest the top from the engine) is the best cylinder and therefore side is financial institution one.
However, many motors right now have cylinder heads which can be placed evenly, that makes it harder to determine which is lender # 1 and which happens to be bank # 2. A number of frequent reasons we need to know this, as an example would be to establish Oxygen detector to switch when you are searching for B1 S1 (Bank One particular Indicator One), or if you’re seeking to track down an ignition coil to inspect for the P0301 (#1 cylinder misfire recorded) misfire code.
