Are these fuel trims ok?

[Jay11]

1998 Ranger 2.5 XLT std cab 72k miles
Rarely driven but mostly in the city. It get's 16.7 - to 18.5mpg, and 21 on highway, about 2 month's back when I did a short HWY trip.

Hey guys I am still somewhere on the learning curve (pro'ly way behind) on fuel trims. Other than an ever so slight vibration or really may be not, (may be it's just me) truck runs fine. I am wondering if you guys can look at my trims and let me know if they are aok. And if not what can you gather from these? There's no CEL, nor codes and all emissions readiness are green.

God I hate torque... you don't have a bank 2 so how is it giving you readings for it.

If you go solely by bank 1 long term, and bank 1 short term those trims are terrific. But who the hell knows with torque, theres data there that physically cannot exist.

Fuel trims are not particularly useful all by themselves as a diagnostic point. They can give a great deal of information about what the system is doing, but unless paired with codes it doesn't tell you a lot.

What are you after here? Do you think you should be getting better mileage, more power, hotter women?

Appreciate your great answers but I wonder you always have your tail up?

Not gonna pass on hotter women. Really I wondered if my trims were ok. Just a out of curiosity. However, I do notice idle going up and down, it doesn't purr on a constant note. Think I need to clean maf, throttle, iac, etc. I am learning that fuel trims are good diagnostics and so I wanted to see what mine are telling me but I am still learning.
