Laurenz brought over the FA5 because it was running rich and had a engine noise at start up.
This is the short term and long term fuel trims.... These are the adjustments that the ECU is doing to make adjustments to compensate for fuel mixture. Shown here it looks like the computer is trying to take out fuel from the fuel mixture. Short term fuel trim is the actual adjustment that the computer is doing at the moment in the long term is the average.
The short term fuel trim Dramatically decreased.... The computer is no longer trying to remove fuel for air fuel ratio Correction. My first time witnessing only one tight valve exhaust valve lash clearance causing a rich code. But by looking at the reading of the (STFT) after valve adjustment indeed one right valve can cause that.
