2008 Ford Expedition Firing Order – It’s crucial that you know which financial institution (or cylinder head) is number 1 to help you decide a starting point for firing order or perhaps to switch the correct part, just like an Oxygen indicator, fuel injector or ignition coil.
Before all of that was needed to determine which lender or cylinder brain is number 1 was to see which cylinder mind is placed the farthest forwards. The one that is easily the most forwards (closest to the front side of your engine) is the top cylinder and that aspect is bank one.
But many engines these days have cylinder heads that happen to be situated equally, making it more difficult to determine which is banking institution number 1 and which can be lender number 2. A number of popular reasons we need to know this, for example would be to decide Oxygen indicator to change when you are looking for B1 S1 (Financial institution One Sensing unit One), or if perhaps you’re looking to find an ignition coil to examine for any P0301 (#1 cylinder misfire recorded) misfire code.
