2004 Ford F150 Firing Order – It’s crucial that you know which banking institution (or cylinder Top) is primary to help you establish a starting point for firing order or just to replace the right part, as an Oxygen sensing unit, gas injector or ignition coil.
In past times all that was necessary to find out which lender or cylinder head is # 1 was to determine which cylinder go is located the farthest forwards. The one that is easily the most ahead (nearest the front side in the engine) is the top cylinder and therefore area is financial institution a single.
But some motors today have cylinder heads that happen to be placed consistently, rendering it more challenging to determine which is financial institution primary and which is banking institution # 2. A few typical motives we need to know this, for example would be to establish Oxygen sensing unit to change when you are looking for B1 S1 (Lender One particular Sensor One), or if perhaps you’re attempting to identify an ignition coil to inspect to get a P0301 (#1 cylinder misfire captured) misfire code.
