N54 constant misfire
Ignition misfire. An ignition system problem is one of the most common reasons for an engine to misfire. As the spark plugs, ignition cables, distributor cap and rotor, and ignition coil wear over time, their ability to transfer the needed spark to ignite the air-fuel mixture inside the combustion chambers becomes compromised. Engine pistons create vacuum on their downward stroke which allows the air/fuel mixture to be delivered into the combustion chamber. (Air only in direct injection engines.) Symptoms of an engine vacuum leak include: check engine light, low idle, high idle, poor acceleration, cylinder misfire and stalling at idle. N54 performance is all about the maintenance.

This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
The most dramatic, stage of the destruction process is when temperatures exceed 2100 deg F. At this point the ceramic begins to break apart or melt or a combination of the 2. It is a constant battle to educate technicians and customers on why their converter needs to be replaced, possible for the second or third time.

4. Use the IGBT negative output and constant power with resistor to drive the IGBT inside the "smart coil" backwards - As above the factory system only has 1 IGBT system that can fail this solution has two IGBT systems that can fail, plus a resistor which heats up and can fail as well. This results in 3 possible failure points.
Apr 11, 2018 · I’m looking for some insight. I recently developed a cylinder 6 and 5 misfire. Cylinder 6 was intermittent under load and cylinder 5 started misfiring intermittently as well but eventually became a constant misfire (Even at idle). I just started running full e85 after installing a double shotgun... The misfire count will increment much faster and eventually it will trigger a check engine light. This constant misfire is something you will FEEL and HEAR with the car at idle and it will be outside of the norm. A quick compression test will verify the internal health of the engine so there is no guesswork in this diagnosis. There is an intersection point between all 3 lines which provide optimal power, efficiency, compression ratio, reliability and cost. Also note that compression ratio is only a single factor in engine performance dynamics. There are many other cost effective engine performance enhancements, for example superchargers.
Jul 14, 2015 · BMW has become aware of a potential problem that could affect the durability of the High Pressure Fuel Pump (HDP) of certain MY 2007/2008 BMW automobiles equipped with N54 engines. It is estimated that only a small percentage of vehicles will actually develop a problem.
