since having my engine replaced with a newer used engine block my idle speed when I first start it up or when it is cold is around 2000rpm which lasts for about 2-3 minutes until it begins to fall to the normal range of 1200-1400 and finally to 850 or 900rpm when warm. how can I fix this or is it okay to idle at 2000rpm for a couple of minutes? is it hurting anything?
thanks.
Sorry I can’t help, the only 9 cylinder engine I ever saw was on a Seagrave fire truck.
that should read 4 cylinder.
