I have been trying to figure it out it started with a slight miss at 3/4 throttle it will set off the alarm and i shut it down for 5seconds and the alarm is off and ready to take off again and if you don't go over 30 mph about 4 thousand rpms it will run all day no problem.I first changed water pump and therostats .I had changed the plugs 3months ago .About 3 years ago i did away with oil injection and mix my own oil.thank you for any thoughts.
