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

SOURCE: 2001 BMW 740iL is sputtering when I accelarate and shaky when idl

A tune-up and throttle body clean-up is a good idea, but mind you on those cars, the valve covers usually leak into the spark plugs and coils, causing the car to misfire. If you are replacing the plugs and find them soaked in oil; replace your valve cover gaskets or you will be back to the same problem soon after the oil soaks the new plugs back up again.

SOURCE: I need to change the oil on my 94 BMW 740IL.

Depends how competent you are here and what sort of tools you have.You will also need to replace oil filter if you wish to replace oil within the engine.The oil has to be drained from underneath the engine and allow it to sit for few hours while draining as this will ensure all the deposits at the bottom comes off.

SOURCE: hello i have bmw 740il 1996

The first thing that you should check is the crankcase ventilation system. You have to be sure that all the tubing and the oil separator and its drain tube are clear and clean. On a 14 year-old car with ~200k miles on it? You are due to need to have that system cleaned out.
If that is not the problem, the prognosis is not good. The other likely problems are all expensive.

I do not have the 740IL manual, but generally the fuel pump relay is either on the right side in the trunk above the battery or behind the glove box. (there is usually a little card indicating which relay it is)

DO NOT CONTINUE DRIVING YOUR CAR. If you can smell fumes, you have a fuel leak and could cause a FIRE. Have it towed to the dealership.
This is a very dangerous situation...
