Question for the mechanics here. Pretty sure these values are in the norm range but are these LTFT numbers an indication of anything I should keep an eye on? I was thinking maybe air filter but I think a dirty air filter would mean negative LTFT. Any fuel additives I should be using?
(Note sure this is diagnostic but I just had the radiator replaced by the dealership)

LTFT at idle in Park after engine warm

 

That should be normal. Especially with any variations of ethanol in the fuel.

 

Those numbers look great. My 2007 GX470 was 3% or less, and that was with 200k plus miles. My 2017 w/ 60k is right around 10%. I think they say anything under 20% is ok.

 

Thanks. I guess I was expecting the LTFT to be very close to 0% given it is the 1UR-FE engine and deviations would be due to carbon, or vacuum leaks or dirty sensors etc. GX is a '13 with 105K miles but I would like to find and correct any early issues, esp since I still have until September 2024 under the extended VSO on the CPO warranty.
