Chris,
I sure hope you're not biting off more than you can chew!
First, the ECU should be allowed to adjust to The Groove before doing all that stuff. I have seen some really strange error codes pop when I tried to do too much too quick. (Your TPS code... Was it there before Grooving? Critical info.) You can't trust what it says...
How about ABS, Generator, and (I can't recall the third) all at once after Grooving? By filling in and recutting The Groove a little further downstream, ALL the codes vanished like a thief in the night. The only things I approve doing (modification wise) are 1) Cut the Groove -and- 2) Cap the PCV.
That brings me to (and is the foundation for) #2. Following the instructions is a real good thing to do. While we feel compelled to jump in and do it all at once, the order of modifications should be followed to master one technique at a time.
Please be patient. The basics of Grooving remain the same, and were put together for a LOT of very good reasons. The first is to teach you as I learned. Second, if your install fails to produce mileage, we cannot accurately diagnose as you have tossed in too many variables and thirdly, the ECU adaptation.
You will become a master, Chris. I think every veteran Groover on this forum will agree with that.
You are probably too young to remember the old TV series Kung Fu with David Carradine. It was a GREAT show, every episode tying together a life experience with a lesson while in the temple learning his art.
His master had one thing he used to tell him all the time.
"Patience, grasshopper."
"Patience."
Great work! Now, I would suggest filling and recutting The Groove with the large bit and quit messing around! THEN watch the fuel trims!!!

PS: I would suspect you have some debris in the connecter for the TPS. Nothing more. So, take the connector apart and clean with spray both male and female ends. If you have air, blow it out when done. If not, then leave it to air-dry. (Blow dryer or heat gun works. Just be sure not to use it near a lot of fumes or we could wind up reading about you in the papers!
