2001 Ford 3.8 Firing Order – It’s vital that you know which lender (or cylinder head) is # 1 to help you determine a starting point for firing order or maybe to exchange the proper part, like an Oxygen sensor, energy injector or ignition coil.
Previously all that was required to find out which financial institution or cylinder go is primary was to see which cylinder go is located the farthest forwards. The one that is considered the most frontward (closest to the top of your engine) is the best cylinder and this side is lender a single.
But some motors nowadays have cylinder heads which can be positioned uniformly, that makes it harder to find out which is bank primary and which is bank second. Several common reasons we have to know this, as an example is usually to decide Oxygen sensor to exchange when you are looking for B1 S1 (Banking institution One Detector A single), or if perhaps you’re attempting to find an ignition coil to inspect for any P0301 (#1 cylinder misfire documented) misfire code.
