I found why you don't touch the little screw behind the throttle body wheel whatever it's called. Well I got the tps set at .50 volts perfect idle now. It ran good in the past but all the gears specifically o/d I'd have to let off the throttle to a tiny bit to make o/d engage. No bad shifts they where a little baggy. But after setting my tps back to spec. All my gears shift amazing way better than before a bit more firm and I never have to let off the throttle anymore. But now the problem is that it won't down shift when I floor it. It down shifts when breaking and all just fine. Example would be I'm in 3rd gear I floor it at 20 and it goes to 2nd and just lugs along. Instead of going to 1st gear like it would before. Now to note if I put it in 1st gear it'll down shift and I use the selector to to shift to 2nd to keep on accelerating at wot. I adjusted the throttle cable as there was play in it. It opens all the way up and closes just how it should. To note I know the procedure is to do this when fully cold and adjust it when it's hot. It did do so but I skipped the cold part cause I had to drive to get the multimeter. Should I redo it? Or did something else get messed up doing so? I'd just hate to do it all over and my shifting goes back to how it was. It's perfect now minus the downshift part.
