Ford 4 Cylinder Firing Order – It’s important to know which bank (or cylinder Top) is number one to aid figure out a starting point for firing order or just to switch the correct part, like an Oxygen sensor, gas injector or ignition coil.
In the past all of that was required to find out which bank or cylinder brain is # 1 was to determine what cylinder head is placed the farthest ahead. The one which is the most forward (nearest to the front side from the engine) is the best cylinder and that area is banking institution a single.
But a majority of engines today have cylinder heads that happen to be positioned equally, which makes it harder to find out which is financial institution number 1 and that is financial institution # 2. A few frequent reasons we need to know this, as an illustration is to decide Oxygen indicator to switch when you are interested in B1 S1 (Bank One Sensing unit One), or maybe if you’re looking to locate an ignition coil to examine for any P0301 (#1 cylinder misfire captured) misfire code.
