The BMW is a high-performance, luxury automobile from Germany's Bavarian Motor Works. Engine problems such as misfires in this elite class of vehicle can be expensive if not caught early. The wise motorist should take meticulous care of their vehicle in order to preserve their investment and driving experience.
Crank Position Sensor
A malfunctioning crank position sensor may throw off engine timing resulting in piston irregularity and impact performance. The manifestation of that problem could be in engine backfires, reduced fuel economy and ease of acceleration. When the sensor fails completely the vehicle may not be able to start.
Spark Plug Wiring
Loss of spark is also a prime suspect in engine misfire. Worn spark plug wiring or a cracked distributor cap in the vehicle may diminish spark plug functionality which would impact all of the BMW's cylinders not just one. The result is in ability to maintain the correct air to fuel mixture within the engine and a misfire occurs.
Exhaust Valve/Head Gasket
Inadequate compression may also display the same misfire symptoms as wiring or a malfunctioning sensor. A blown exhaust valve will cause an air leak which will impact air to fuel mixture the same as a cracked distributor cap. A cracked head gasket will cause at least two cylinders to misfire and will require significant repair if it is the culprit.
