Seems like theres a build up of carbon in the intake. you can try the pour in gas tank cleaners for fuel injection cars which you have and after 2 or 3 of those with 2 or 3 full tanks it will clean the injectors and the carbon out of the intake. And if you really want to get them cleaned up even better and stop all the rough idling, take the intake off yourself and clean all the black stuff off anywhere you see it. Thats the carbon build up. Especially on the butterfly valve area. It will not only run better for you but get better gas mileage as well.

SOURCE: Car hesitates/stalls when engine is warm and car starts to move.

Sounds like a bad motor mount, pop the hood and see if the motor shakes or moves rapidly when u put it in gear holding down the brake.

Your oil is a little low, and the timing may be off a bit but if it smooths out after warm it is probably ljust

SOURCE: bmw e36 328i cuts out at idle,wont krank,runs rough at idle.

The battery could still be bad and if you don't have a totally good battery in the car it won't run right. Take to one of the parts stores and they can check it for you for free. Probably as simple as a battery.

Why is my1997 bmw Z3 1.9 start rough for 2min then is ok


The EGR valve opens when the engine is warming up, which allows exhaust to enter the intake manifold. This is essentially "extra air" coming into the engine. The engine has an "idle speed control" function, which is either a solenoid or small stepper motor connected to a valve that allows a controlled amount of air to "sneak" by the throttle plate in the throttle body. Fundamentally, it is the amount of air entering a fuel injected engine that controls engine RPM. A defective idle speed control ("ISC) motor or solenoid can cause the problem you stated. (I do not know which type is used in your BMW.) Often, a check engine light will illuminate of the engine computer cannot adequately regualte engine idle speed.

A/c doesn't work, temp gauge doesn't work, speedometer doesn't work until it gets to 30 mph, and rough idle in the mornings. could all this be the result of a bad computer?


Very unlikely that it would be a computer problem, it does not control the A/C, or temp gauge. Sounds like multiple problems. A/C could be just low on Freon, if pressure is low, it will not turn on. Temp gauge and rough idle may be related, if temp sensor is bad, the computer wont know the engine temperature and thus not mix the fuel correctly. But there are many things that can cause rough cold engine idle, like dirty throttle plate, or bad idle air control valve. You did not say what engine you have, so this is just general information.

Want idle on cold mornings.


Thinking possibly the air temp. sensor (mounted in the
air cleaner housing) Really need to see scan data to tell for sure
but that costs a fortune at a dealership.air temp sensor is fairly
cheap.

White smoke came from the exhaust pipe and the car killed in motion. I check all fluid levels were fine, once i started the care again and proceeded the accleration was a bit rough. After a few minute


white smoke mostly is caused by over fueling so what i suggest you do is first of all check if there is no leak on the injectors and if there is none which means your valve sterm seals are damaged.When the head gasket is blown out you may have problems like :-loosing power when driving,over heating,idling problems and oil mixing with water, its not your head gasket.
