Also, how does LTFT differ from Short Term Fuel Trim?

Sorry Im full of questions trying to figure this out, lol.
Yes any time your LTFT show negative the PCM is taking fuel away(telling the injectors to spray less), you can scan your IPW's(injector pulse width) to see what the injectors are doing.
-23.4 is what you said your LTFT's read after you lifted from WOT so why are you asking -23.4...what?
You can't remember what you wrote...or what? LOL
