Hey guys, I have been experiencing issues with my car now for over a month now. I have attached an image of data obtained from "Torque" app via OBD, when car is at idle

Things i have eliminated as to possible cause to the problem
  • Ignition Coil (all good)
  • Spark Plugs (brand new)
  • New Fuel Pump
  • New Fuel Filter
  • MAF Sensor checked its good

Also at idle you can hear a very light hissing sound from the intake manifold. I have checked my vacuum lines, all good good. It has all the symptoms of a car running too lean but only when under load.

As you can see the fuel trims on bank 1 do not look correct, also AFR is off. Would appreciate any idea or suggestions please.

Thanks guys
