Hi all, I have a D40 which breaks down/misfires between 1000-1500 rpm. After that it revs smooth and strong. The car has been sitting for a while after engine swap (used). Has new timing chains, fresh fuel, new fuel and air filter. I have cracked the fuel lines to bleed any air out of the lines. Interested to hear from anyone who has experienced this problem and found the cause.
