Thanks for the clarification of the data.

Timing changes are negligible, possibly knock sensor(s) triggering slight retard on timing?

Fuel trims are a bit wacky. Would like to see what the pre Cat O2 sensors are doing.

O2 baseline Voltage is 0.45 Volts when cold/inactive, this is as expected.

Not sure why you are not picking up pre Cat O2 sensors? Do you have another car you can try ELM327/Torque Pro on? Assume you also have the Torque Pro add-ons as well?

If your pre-cat O2 are original, suggest replacing just because, as they are considered consumable anyway. Usual replacement mileage is suggested at 100k, but I replace at 75k as most drivers in urban areas have engine idling for long periods in traffic. Bosch are usually about $50 on Amazon, I have good luck with all the Bosch I have purchased from Amazon.

Sorry if my English is questionable, it is my native tongue. Maybe it is Virginia coming through?

I just multitask quite a bit as I do a lot of network and remote support and I have a lot of distractions with kids and other things, so many times I am in and out both physically and mentally!

I try to contribute where I can.
