Does anyone know what these spikes in the graph could be? I have no idea what thats suppose to mean. I was told that the car needed a tune-up possibly. Is that what I am seeing in the graph? Thanks in advance.
I bought the car with 44k and i have 65k roughly on it. Haven't changed the plugs or wires but its probably time and the fuel filter too.
