What is the mileage, and is your vehicle experiencing any issues?
111000 miles. No issues
Pretty much normal for that age vehicle no real serious problems you might just check for any kind of vacuum hose leaks they get cracked and sometimes leak over time
See below to understand those numbers better: You will need to look at a car repair service manual to see what the acceptable lower and upper bounds should be. Ideally, you want STFT to be within +/-3% and the LTFT to be steady around 0%. Some deviation from this can be OK, but general rule of thumb is when you add STFT and LTFT together you want to be within +/-10%.
