1999 Ford F150 Firing Order 4.2 – It’s vital that you know which bank (or cylinder Top) is primary to aid decide a starting place for firing order or perhaps to change the proper portion, such as an Oxygen indicator, energy injector or ignition coil.
Previously all that was required to determine which lender or cylinder mind is primary was to determine what cylinder mind is placed the farthest forwards. One that is the most forward (closest to the front side from the engine) is the top cylinder and that side is bank 1.
But many engines right now have cylinder heads that happen to be situated equally, making it more difficult to find out which is financial institution number 1 and which can be banking institution number two. A few common motives we have to know this, as an example would be to figure out Oxygen indicator to exchange when you are searching for B1 S1 (Bank One Sensing unit One particular), or if you’re trying to track down an ignition coil to examine for any P0301 (#1 cylinder misfire documented) misfire code.
