Has anyone ever had their fi light come on every few mins on an F4i ? When it does come on it kills the engine for a second

 

You are losing connection to something, somewhere.

Make sure no wires are pulling out of your ECU, make sure your battery connections are good, make sure all your plugs are pluged in all the way and none of the wires are getting stretched



Mine did the same thing for 2 years.. Ended up being the kill switch wires on the main harness were bad.. I had to splice it and get rid of the kill switch
