2002 Ford 4.2 Firing Order – It’s essential to know which bank (or cylinder head) is # 1 to assist establish a starting place for firing order or perhaps to exchange the right component, like an Oxygen detector, energy injector or ignition coil.
Before all that was required to determine which financial institution or cylinder mind is # 1 was to determine which cylinder mind is positioned the farthest frontward. One which is the most ahead (nearest the leading from the engine) is the top cylinder and that part is lender one.
But many engines today have cylinder heads which can be placed uniformly, that makes it harder to determine which is lender # 1 and which can be lender # 2. A few common motives we have to know this, as an example is usually to establish Oxygen detector to exchange when you are interested in B1 S1 (Lender One particular Detector One particular), or if perhaps you’re attempting to track down an ignition coil to inspect for the P0301 (#1 cylinder misfire saved) misfire code.
