1999 Ford Explorer 4.0 Ohv Firing Order – It’s important to know which lender (or cylinder Top) is number 1 to help you decide a place to start for firing order or just to switch the appropriate part, such as an Oxygen sensor, gas injector or ignition coil.
In the past all that was essential to determine which financial institution or cylinder brain is primary was to determine what cylinder mind is positioned the farthest forwards. The one that is easily the most frontward (closest to the front in the engine) is the main cylinder which part is bank 1.
But a majority of engines right now have cylinder heads that are positioned equally, making it more difficult to find out which is bank number 1 and which can be financial institution # 2. A couple of popular reasons we must know this, as an example would be to determine Oxygen sensing unit to replace when you would like B1 S1 (Financial institution One Sensor One particular), or if you’re looking to track down an ignition coil to examine to get a P0301 (#1 cylinder misfire saved) misfire code.
