Throttle position system problem!

[Firehawk N Wv]

My car is in the shop. I was driving it day before last and all the sudden it droped form 25mph to 10mph, my SES light came on as well as the Reduced Engine Power light. The car wouldnt turn over more than 2grand. It is now at Moses Pontiac and it is what I and the guy who tuned my car thought it was after we checked it with his lap top. It was the Throttle Posision Censor in the TB and it was also the Tachometer censor in the throttle pedal. As my car dont have a throttle cable. Its an electronic fly-by wire. I should have it back on the road Monday and the cam tune back in it Thursday.

Would this have anythign with us turning the torque management off?
Do many of you guys turn this feature off when you tune your cars?

Even though noone has posted to talk about this subject.

They luckilly got the car done today. They were able to get the parts need locally from another GM dealership. So I have a shiny new TB and a new Accelerator pedal setup. Ill pick her up in the morning.

I picked up the car this mornign and drove like nothing was wrong. I got off work and went to the gas station to get gas and I saw steam coming from under the hood and out of the headlight doors. Looked under the hood and saw that my TB was leaking coolant on the bottom. So they either didnt clean all of the old gasket off or they forgot to put one on at all. I have some gaskets with my TB spacer aht Im going to fix tomorrow after work. I will have to drive with my radiator cap loose as not to presurize the system.

Re: Throttle position system problem!

Got the TB spacer on and the problem fixed with teh leaking. Then a day later I went to retorque the nuts and broke off the upper stud. Had to run to Advaced Auto to get another stud/bolt and fised that. Now I have to retune for the new MAF and the spacer.
