Change the injectors on a bmw
This is not a job for the untrained or inexperienced. The system stores high pressure fuel which has to be taken care of. There are cleanliness issues to address, engine needs to be clean. All areas of connections, pipes etc need to be clean. There maybe special tools needed. You don't say why you are changing them, if the servicing has been done correctly they can do 150k with no problem. You will need a manual to ensure all steps are done properly and safely unless you have experienced help.

any check engine light on? do you see the check engine light up when you first turn the key with all the other lights then it goes out when you start the car this is the cars system self test done by the computer if you do not see the check engine bulb light up it is burned out and I'm sure when replaced with a new bulb it will now be lit all the time because there has been a trouble code set involving the throttle position sensor or the Idle air control valve these both control the idle speed of the engine and your car rough idles and then the computer gets that info after 2min.and then it compensates the values to get it to run when the check engine light is on your system is in what is called open loop this is a program that all cars have that allows you to get to a service center for repairs there is also the possibility that some one turned the throttle body screw back to lower the idle and when it starts cold the computer learns there is an error and does it's own fix check this stuff out and post back good luck and understand I am not in front of your car and I'm trying to think without seeing it
Check engine light on 1998 Z3 BMW
BMW engine light
Comes on if DME engine management system self diagnostic fault detected. Will stay on until codes are called up and memory erased.
With OBD read the code as follows. Turn on ignition key, press accelerator pedal to the floor five times within 5 seconds. The check engine light will remain on for 5 sec , blik off, come on for 2,5 sec, go off for 2,5 sec and fault code will begin to flash. If more than one fault exist 2nd fault code will be separated by 2,5 sec pause. after fault codes there will be a 0.5 sec flash and light will remain off. to read codes again do procedure again.
Canceling of codes. make sure fault code is present (short blink and light goes out for long period), depress throttle pedal for at least 10 sec. read fault codes again and check for code 1444 (no faults stored.)
Check also the following, fuel pump, oxygen sensor, fuel injectors, engine coolant temp sensor, idle speed control valve, mass airflow sensor and too many other things.
Battery keeps going dead. Put new one in.
You have a Drain on your Battery. The Nominal drain during the night is 50mA. Anything more than that and you have a issue. Put a Multi-Meter on your Battery (Between your Battery and your One Terminal's and then one on the Wire itself (Disconnect the NEGATIVE Clamp). MEasure the AMPERAGE DRAW...Then disconnect one fuse at a time and if the number does not go down. When you get the DRAMATIC DROP, then you have found what system has the draw (test all just for a Piece of mind).Then once you discovered which system, then you need to dig into that system to define it down to the problem and fix it and then you will have your issue resolved.Good Luck
