Cold Starting - BMW Forum

CaptainEL · 01-05-2004, 06:19 PM

First of all Hi.
I am having trouble with my 525i se 1990 G Manual BMW.
When i start it from cold it starts fine and ticks over ok but as soon as i touch the accellorator (Probably spelt wrong) it is as if the car is running on 5 cylinders it miss fires. But when it warms up it is fine????
Also not sure if this is relevent if i turn the car off after i have run it for a while for more then 5 minutes it just keeps turning over for ages before it starts or i turn it over stop then do it again then it starts.???

Any help would be appreciated. (Have been told it might be the non return valve in the fuel pump)

welcome to bmw forums.

yeah it could be the non return valve but thats a long shot..

check out your plugs and service records see when the last tune up was done..

The car was owned by my brother who had it tuned and i put in new BMW spark plugs only 3 months ago????
But then saying that i had to put a new throttle housing hose as it was split so the tuning might be out so i will try it thanks.
