My 2000 200hp Ficht running real rough stalls unless I raise the idle a little,put the computer on it and no codes did cylinder drop test and #1 cylinder not firing.I did not have a spark tester with me so dont know if plug has spark I will test that when I go back figuring a bad coil,I do have a new one if it is.What else could it be besides coil.Diagnostics says injectors are firing.
Thanks for any help
