1997 BMW 528 Rough IDLE

Thank you for replying so quickly right not my car is in my class we are on winter break now. I wont be able to get to back to my car until JAN 6. As soon I get it I will send you the code #.

Ok I got my running. Its runs a lot better then it use to but still having idle problems when I turn it on when I rev it pass 2000 rpms it stabilizes it self.
When I drove the car it was driving great except for the brakes it felt when the idle goes down the brakes do not work takes along time for it to stop with my foot on the floor. What could this be a vaccum in the lines? I haven't checked the fluid level of the brakes yet that's something I will be working on tonight checking if the master cylinder still good.

The codes that my car is giving off is

P0173 : Fuel trim (bank 2)
P1189 : Fuel Control (bank 2 sensor 1)
P1188 : Fuel Control (Bank 1 Sensor)
P0170 : Fuel Trim (bank 1)
P0340 : Camshaft Position Sensor

I have changed the gas the spark plugs the coils the crank shaft and cam sensor fuel filter, fuel pump, sending sensor relays.

I Also am suspecting a gas leak when I drove the car there was puddle of gas underneath the car but when I put it in the garage to check I revved the car drove it around a lil more let it sit and idle nothing was coming out I checked under the car nothing was wet im thinking that a low pressure return fuel may be the culprit and also the for the rough starting idle.

Thank you

This may seem like a stupid question but ive decided that while im putting the new manifold gasket im going to change the injectors ive reading up on them seems like the seals get brittle and can cause vacum as well besides they havent been changed as fas as I know 160,000 miles

im reading up on this but it seems the remanufactured injectors are much cheaper would you reccommend remanufactured injectors or is it just better to get brand new ones I just dont want problems later with the engine just wanted to know if you think remanufactured is reliable?

Yes I already got the new o rings just kinda figured they are old injectors maybe a good idea to change them while I have access to them now so I dont have to work twice later on

I have changed the hoses that go from the vanos to the crank case ventalation and the hose the goes from the bottom of the crank case to the oil dipstick it fixed the rough idle considerbly but it still has a vacuum when it starts still starting rough until it get enough vacuum and runs ok still loses vacuum at times while braking at times I suspect it to be another leak I have not been able to detect with carb cleaner. Was wondering if you had any ideas of where else these type of cars have common leaks

codes that popped up on the car yesterday

Po 111 IAT Sensor CKT range/performane

Pending: Po 340 crankshaft postion sensor A bank 1 circuit malfunction

Pending: Po173 fuel trim malfunction (bank 2)

Pending: P1189 bmw code dont know what that is

Pending: P1188 bmw code

P170 fuel bank trim malfunction bank 1

im also wondering why the blower on the car never stops now after turning off the car the only way to stop it is to disconnect the battery everytime the car is parked. Im thinking I may need a new ac control unit because the air when on is stuck on one setting which is the highest no matter if u have the lowest setting it just blows hard all the time blows cold only when it wants to.
