2003 Ford Explorer Firing Order – It’s important to know which financial institution (or cylinder Top) is number one to help determine a starting point for firing order or simply to replace the right aspect, as an Oxygen sensing unit, gas injector or ignition coil.
In the past everything that was required to determine which banking institution or cylinder head is primary was to find out which cylinder go is positioned the farthest forwards.

A couple of popular factors we have to know this, for instance is to determine Oxygen sensing unit to replace when you are looking for B1 S1 (Banking institution A single Detector 1), or maybe you’re attempting to find an ignition coil to examine to get a P0301 (#1 cylinder misfire documented) misfire code.
