Re: E21 323i - cold start problems

Hi there,

I have a 1980 323i which is in perfect condition.  During this winter 
time, however, it has a lot of trouble starting the engine.

In the early morning, it usually takes me two or three times to start 
the car. (Sometimes it even takes 5 or 7 times in really cold 
weather.)  Once the engine is running, the engine usually cut off at 
the first traffic light /intersection as I stop and go.(the car just 
stall)  Perhaps there is lack of power at low rev when the engine 
hasn't been warmed up.

But it starts and run perfectly once it reachs the operating 
temperature.  And this usually doesn't happen in summer.

The car have already checked by BM specialist and they claimed that 
there is nothing wrong with the injection system. (ie cold starts 
value, additional air slide etc.)  He recommended that decarbonising 
each cylinder head and clean the injectors will cure the problems.
As the car getting older, carbon build up in the cylinder.  

However, I wouldn't know whether it is worth to do it. (Quite 
expensive!!)  Will those injectors cleaner solution fix the 
problems? (I've already try once but it doesn't get any better).

I should be grateful if any BMW owners could give me some advice on 
this.

Thank you,

LEON.
