STFT's look decent.
But LTFT's are really high.
Did you ever fix a vacuum leak recently?
If so, can you reset the FT's on your Innova?

Also, how old are your fuel injectors?
Have you ever cleaned them?
What about fuel additive, have you ever used it?
It removes carbon in the cylinders and on the valve stems, so it's important to do that once a year.
I use BG44K and Jectron.
Techron used to be good, but now it sucks, since the EPG got involved a number of years ago.
Incidentally, contrary to sales hype and other misconceptions, fuel additive doesn't clean injectors.
In fact, if it breaks loose junk in the fuel system, that'll clog injectors (the small screens inside).
And induction cleaning isn't that effective either, esp. if you have PCV oil saturation issues, as many vehicles do today.
So if your fuel injectors are not delivering enough fuel, then it'll screw with your computer and you'll get strange readings that seem like vacuum leaks.
Or, if your fuel pressure on the rail is low, you get the same sort of low delivery issues (weak fuel pump, clogged fuel filter, bad fuel regulator, etc.).
Another possible leak point could be the IAC valve.
And if the throttle body isn't working right, then it'll throw off the computer too.
If it's dirty, then that'll give you fits as well, but usually related to idle.

All vacuum leaks were repaired. I replaced the intake gaskets, valve cover gaskets, pcv valve and elbow, dpfe sensor and hoses, as well as whatever the big vacuum line tha comes off the intake and connects to something under the battery, i believe that goes back to the charcoal canister. All that was replaced about 2 years ago. Yes i can reset and clear any codes with my scan tool. I already did that the last time it acted up. As far as i know injectors are factory. I have a can of seafoam in the tank atm. Usually run it or lucas fuel injector cleaner about once or twice a year. I dont have a fuel pressure gauge to check that atm, but i replaced pump and filter, which was also the next to last oil change so maybe about 8k ago believe it was last year. Throttle body is clean, usually remove and clean it once or twice per year. I only put about 50-60 miles per week on the truck...benefit of only living 2.5 miles from work.
