so im having this problem. like the title says my fuel cuts out a 5500rpm so says the air/fuel ratio gauge. it used to be a 6000. well the hell is going on? does it just keep dropping every month. any help would be great thanks.

 

bump

 

Check the fuel pressure not using the gauge. Maybe its not the fuel pump, maybe the gauge is off a bit? Not sure if its possible but I would check your pressure elsewhere.
