2003 Ford Focus 2.0 Firing Order – It’s essential to know which bank (or cylinder head) is number one to help determine a starting point for firing order or maybe to replace the proper portion, such as an Oxygen sensor, energy injector or ignition coil.
In the past everything was necessary to determine which banking institution or cylinder brain is number 1 was to determine which cylinder go is positioned the farthest frontward. One which is regarded as the forwards (closest to the front side of your engine) is the number one cylinder and that side is lender one.
But some motors nowadays have cylinder heads which are situated equally, that makes it harder to find out which is bank number 1 and which is banking institution number 2. A number of common factors we need to know this, for example is to decide Oxygen detector to replace when you are interested in B1 S1 (Lender A single Detector 1), or maybe you’re seeking to find an ignition coil to inspect for the P0301 (#1 cylinder misfire saved) misfire code.
