SOURCE: misfire on cylinder 4 & 5. combustion miss with cylinder cutout.

the best way to diagnose a misfire is to move the ignition coils of those cylinders(4 and 5) to different cylinders to see if the misfire will move. you can also move the injectors around and even the spark plugs.(make sure to keep a good record of where you are moving them). if you can't get the misfires to change cylinders. your next step would be to do a compression check on all cylinders. air leaks in the intake system can cause misfires but usually it isn't on the same cylinders all the time

SOURCE: 96 bmw 740il misfire

This is a pretty common problem. I would change your valve cover gaskets. They run around ~ 50 bucks. If they are bad it will leak oil into spark plug well and cause a misfire. Very known on the 740.. Also if tune was not anytime not too long ago id change spark plugs while you at it. Then clear the computer and if you still get misfire on 8 try changing the ignition coil which is right about the cylinder with cylinder ignition coil 5. clear the computer. if you get random misfire and misfire cyclinder 5 after then its your ignition coil. parts store runs around 100 bucks

I HAVE A 2006 BMW Z4 3.0I ROUGH IDLE.. SET CODE # PO305 # 5 MISFIRE..SO I REPLACED THE COIL AND PLUG WITH A NEW SET. STILL ROUGH IDLE BUT NOW WHEN STOPPED AT A RED LIGHT WILL DIE.. CODE GONE NOW BUT??


code p 0305 is the no 5 cylinder misfire and included in the list of causes are plugs and wires but unfortunately also in the list of causes are== injector, injector connections and wiring and this is the most common area of the misfire and not the plugs or ignition circuit
pull and check no 5 injector and place it in another cylinder and see if the fault moves to the new cylinder
if it doesn't move it is in the wiring and control
if it does move , replace the injector

Will a EML light come on on a 2001 BMW 525i if it has a bad fuel filter?


I would assume that if the engine control module monitors the fuel pressure in the injector rail , then yes .


otherwise it will more that likely cause a random misfire in cylinders or even maybe a steady misfire in cylinders. because your fuel pressure is too low.

Replace spark plugs and look at coils. Sounds like a misfire at idle. Car is trying to keep idle high enough with 1 or 2 cylinders misfiring. Car compensates then revs up as the cylinders catch and run again. These cars often have bad coils. Scan car and look for codes 301 through 306. Replace all plugs and if misfire comes back then replace the coils on the cylinders that occasionally misfire. Look at boots and spring wires on coils and replace coils that have bad boots.

Adding transmission fluid to 1992 BMW 525i.


On the driver side of the transmission pan there is a fill plug. The car must be in the air and level. With the car running fluid will run out of the plug hole when it is full. This is no fun without a lift.

Overheating


you might have a blown head casket try due a pressure test on each cylinder and sometimes you can take a spark plug out 1 by 1 and just tap the ket so it cranks and see if water comes out of the cylinder
