Okay, the numbers look pretty much the same as yesterday. At some points I noticed the Calculated Load reaching 97.25 percent. That was at about 2300rpm, MAF 32.82g/s.
Then another spot was at Calculated load of 91.76 percent at 3000 RPMs, 97 percent is extremely high, for 11mph (19km/h). Does the vehicle feel very sluggish, can you do a wide-open throttle run, such as getting on a highway and see what the highest RPM you can reach and then let off the gas. Not hold it at that highest RPM but just to see what you can reach and record the live data, rpm, MAF, Intake Air Temp. I can go through the data on your videos and find the highest rpm like I have been so far. But I would expect the vehicle to be very sluggish if these readings are correct. Not being in the vehicle with you, I can only go by the data numbers I see.
But having the Catalytic Converter back pressure tested is one of the first tests to do. Just because over the past year dealing with the Evap system not functioning correctly, it could have overwhelmed the Converter over that amount of time.
This is a Volumetric Efficiency test (VE test) with the numbers you had, and 3000rpm was the highest I saw, and the EST_VE is the results of that test, 51.47%. Thats technically how well the engine is breathing, taking in air and allowing exhaust out. It's possible the scan tool data is not entirely correct, but you did notice a low mpg, and is there a code stored in the engine computer?
At the top there, MIL ON DTC count: 1 (code stored),
Catalyst: Available/Not completed, Evap System: Not Completed.
So, the Readiness Monitors have not been able to pass the self-tests. For some reason the Evap has not either, but the Evap Monitor has to be certain conditions to run its self test. Most have to have a certain amount of gas in the tank, a certain amount of cold soak (off time) has to have gone by, things like that.
So, I'm more concerned with the Catalyst not being complete.
