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)
