Just when you think everything is going ok something always cones up with moding cars.

I drove the car off boost for about 30 min today and when i went to accelerate from a stop sign the pedel got really musshy abd the car would not go.

I limped it to work and it only accelerates with 1-3 % throttle input.

I tor everything apart at work and rechecked the tb cables and then cleared the code and all is fine now.

Has this ever happened to anyone? Its a scarry feeling driving behind someone thinking your car might decide to go wot on you from a faulty throttle pedel

He throttle pedal assembly is know to go bad. I would also check the connection by the throttle pedal assembly.

I once went WOT and the car felt as if it stalled as soon as I mashed the throttle and did not accelerate...I thought I blew my engine for a moment ( scary ) I got off the throttle and then it just went away on it's own. These cars are beasts, beasts get quirky sometimes.

If it comes up again ill take it to the dealer.the check engine light came on in like 15 seconds after it got mushy.

I had my car sitting in my garage for a few weeks. I went to drive it for a real short trip and it ran like garbage. Coughing and sputtering; it even stalled after I pulled out of my driveway. It felt like I had some bad fuel. I drove it again later, seeing if a few miles would help it out, but it didn't. Funny thing was, it seemed to run fine at speeds over neighborhood speed.

I checked the codes and there was a P2121. Never saw that one before. I was getting ready to change the O2 sensors anyway, so I just disconnected the battery while I did it. After reconnecting the battery, she's running like there never was a problem. Also, changing those upstream O2 sensors made a huge difference. It starts, runs, and idles so much smoother now.

O2 sensors / you have a warranty so just go to the dealer.

I have brand new o2's waiting to go in too, I feel after a while it's good maintenance

My bet is on this; replace the pedal assembly with a new one and see if that fixes it. Mine went bad and the car would stall whenever I floored it and then the car would hardly accelerate with any pedal input until I restarted it. Replaced the pedal and all was good again.
