As the title says, as soon as I go WOT in any gear, 90% of the time, the car will stop accelarating. If I let off the gas immediately, the car will idle, but will not respond to the throttle unless I restart the car. If I don't let off the gas immediately, the car will stall as soon as my foot comes off the peddle. The car runs normally after I start it again, until I go WOT again.

 

I would guess throttle position sensor. But i"m sure someone knows more about this then me.

 

I thought that as well, considering I was getting P0123 - TPS voltage input high. I put in a keifco TPS and that stopped that CEL from coming back on. But I'm still having the car stall at WOT. The TPS is tested and working as according Webtech. I also hooked my computer up to the car and it shows the TPS matches the RPM's and MAF readings at each level.

 

do you currently have a cel? how did it act before vs. after swap, was it a new part?

 

Currently, no cel. I didn't notice too much of a difference after the swap. It did keep the ECU from throwing the P0123 code though. The TPS was brand new in the box.
