Question about 2003 BMW 325
I have one of those BMWs and they are the most unreliable cars. Too many non-functional badly designed sensors and buggy engine management software that can function without problems for a few month. Mine is 6 years old and the dealer for the last two years could not figure out why I am getting misfire, one time on cylinder 3, another on cylinder 4. They just keep swapping coils, injectors, they even reloaded the engine management software, according to them. I still get it. The dealer just kept in fact just erasing the error but could not really fix the problem. The car also leaked coolant and oil just after the extended warranty expired. If you have one of these cars without warranty, expect to spend $2000 to $3000 every year just to keep it running. My 4Runner did not cost me a penny for 8 continuous years, just basic maintenance but no repairs.
Google BMW misfire or E46 misfire and see for yourself. Man, you will get zillions of results descrbing the problem with no answer. It is all gussing but no real answer to the problem.

"EML" is an acronym for "Elektronische
Motorleistungsregelung". Loosely translated from the original German for the BMW
owner means Electrionic Engine Power
"EML" is BMW's system name for electronic throttle management. The "EML" system, in it's most basic sense consists of an accelerator pedal (with an electronic position sensor), a computer module (usu. integrated with the main engine computer), and an EDK (Elektronische Drosselklappe or Electronic throttle valve). The EDK is also known as a "drive by wire" throttle. "EDK" throttles use a computer controlled stepper motor rather than a purely mechanical linkage (usu. metal cable attached directly to the accelerator pedal) to control the opening and closing of the throttle plate.
"Drive by wire" throttles are very common
on modern vehicles starting in the late nineties up through the present day.
"Drive by wire" technology enables very precise throttle control to improve
drivability and vehicle emissions, as well as many convenience features like
electronic cruise control, traction control & stability control.
BMW first implemented "drive by wire" in very limited quantities on the most expensive & sophistocated BMW models starting in 1988.
The latest generation of advanced vehicle
features to take advandage of "drive by wire" technology are radar guided cruise
control, accident avoidance control, autonomous-driving, and autonomous-parking
