99 Ford Explorer Firing Order – It’s important to know which lender (or cylinder head) is # 1 to help figure out a place to start for firing order or perhaps to switch the correct component, just like an Oxygen sensor, fuel injector or ignition coil.
Before all of that was required to find out which lender or cylinder mind is primary was to see which cylinder head is placed the farthest forward. The one that is regarded as the forwards (nearest to the top of the engine) is the number one cylinder and this side is bank a single.
However, many motors right now have cylinder heads that happen to be located equally, which makes it more challenging to determine which is banking institution primary and which can be bank second. A couple of popular reasons we need to know this, as an example is always to establish Oxygen sensor to change when you would like B1 S1 (Banking institution 1 Sensing unit One), or maybe if you’re attempting to find an ignition coil to inspect for any P0301 (#1 cylinder misfire saved) misfire code.
