Hold up, I wouldn't count it out that fast. I finished a rebuild a couple of weeks ago and have been trying to figure out why my car wouldn't start and idle until yesterday. I have a SAFC installed and I knew I wasn't getting a reading off the TPS, but I wasn't too bothered by it because I figured, like Keithrulz, that I've run the car without the TPS before, and it always worked fine. In this case, I could start the car by pressing the gas pedal, but it would always die if I let up, and never got anywhere close to idle.
I went out and adjusted all kinds of crap to get the car to hold an idle, and it wouldn't idle lower than 2200 rpm or it would die. So I decided to move on to the TPS problem, broke out the wiring diagrams and starting ringing out wires on the multimeter because it was acting like a broken wire. Finally got everything straight on the TPS, went and started the car and it started right up and began running itself up to 4000! I killed it real quick and readjusted by idle back to about 2000 and started working it down again and now it idles around 1000 again (with no emissions) but surges. The only thing I changed was the TPS (I actually had it plugged into the wrong connector.) :P The right one was tucked down behind the water pump housing, and I managed to get it connected to the green one by the MAF.
It's not that much work to get a multimeter and ring out those wires on the ECU, make sure everything is getting where it needs to be. If that's really the only thing you've changed, then that's probably where the problem is. Good luck!
