Going to test that tomorrow, both press de gas a quarter, half and full.Yeah, didn't understand that graph either. I suppose the vertical axis is TPS value? While looking at the graph or screen, press the gas pedal about 1/4 way and the TPS should be 25%. Ditto for 50%, etc. Should be pretty consistent.
Does your app allow you to record data? Go for a drive and then review information such as fuel trims. I'm certain a misfire will cause fuel trims and O2 sensor to show some spikes or dips of some data. At least it will hopefully give you an idea if the problem is on bank 1 or bank 2.
Yes it does record data, will do a recording and get back to you, doesnt understand that much of fuel trims and O2 sensors to be honest, or atleast not the readings from them.
