Hi,
My 1997 115HP Johnson V4 fitted with carburetors and opto ignition has an intermittent fast idle problem.
This motor generally runs well however on occasion the idle increases to 2000rpm while in neutral for no apparent reason.No alarms are present on the LED and warning horn system.
This generally occurs after a period of running when pulled back to neutral but also on restart of the engine.
The engine operates in water temp of approximately 20 degrees Celcius.
I am aware of the engines SLOW condition (rpm limited to 2500) however this is associated with high engine temp.The engine also has a quickstart function however this is meant to operate to a max rev count of 1250rpm for 5 seconds.
Any ideas ?No WAGs please.
cheers PP
