2006 Ford Expedition 5.4 Firing Order – It’s essential to know which bank (or cylinder head) is number 1 to help you decide a starting point for firing order or perhaps to exchange the right aspect, just like an Oxygen indicator, fuel injector or ignition coil.
Previously all of that was necessary to determine which bank or cylinder mind is # 1 was to see which cylinder head is placed the farthest forward. The one which is the most frontward (nearest the leading of the engine) is the best cylinder which area is lender a single.
However, many motors these days have cylinder heads that are situated consistently, which makes it more challenging to determine which is financial institution number one and which is bank number 2. A couple of frequent reasons we should know this, for instance is always to decide Oxygen sensing unit to exchange when you are looking for B1 S1 (Financial institution One particular Sensor One), or if perhaps you’re seeking to find an ignition coil to inspect for a P0301 (#1 cylinder misfire saved) misfire code.
