Ok so I fixed my sputtering problem by switching out the TPS again for the second time. Well I got gas the other day and started my car up and pulled to the intersection to pull out and it dies in the intersection. So I crank and crank and crank to no avail. I then push my car off to the side and go over everything and it all looks in order. Still no start. So I check codes and pull a 41. TPS go figure. I had been buying them from O'Reily's so I called up toyota and had them order me one. Put it on today and go to start it up and it just cranks and that's it. Pull codes again. Code 51 and nothing else. Back when I first got my car the A/C didn't work so my Grandfather hardwired it to a toggle switch. But I dont' see how this could affect anything b/c my car has ran fine since then. I'm kinda lost in what to check. Someone shoot me an idea of what to look at. Thanks Bill.
