I am hoping someone on here can help me I am having some major problems with my 03 Monte Carlo SS. I have spent hours on here looking and reading and some stuff is similar I am not really finding anything super close to the problems I am having. The check engine light is not on however the ABS light and Traction Control LIght are on for a faulty Front Right Speed sensor. I do now know if that will cause all of the below or not.

Mechanics around me will not look at it as they are calling it an intermetent problem and without the check engine light being on it would take to long to diagnose if they could at all.

130,000 miles on Car
Car Starts and Idles Fine
Car is shutting itself off at Speed Car Still has Power to Everything Just Shutting itself Off
When it stalls it will restart as soon as you put the car in park will die and than as of now run again until it decides to stall again.
When pressing the accelerator to get up to speed the RPM will jump back and forth untill you release the gas pedal and slowly push it back down.
When you take your foot off the accelerator the engine RPM does not drop and car does not lose speed until 5 or seconds and then it will lose speed and RPM's will slowly drop to normal.
Car feels like it misfires right before it stalls. As soon as I take my foot off the accelerator the RPM's will drop to zero and stall
The cars shift points feel off.
Here recently the car is not realy wanting to shift at all and the RPM's are way off think 3500rpm at 30 MPH and no throttle response at all. And the car does not feel like it is at 3500 rpm's it just thinks it is.

Can anyone point me in the correct direction please.

Welcome to CT. No quick answer here. A tech would have to drive the car with a full function scanner connected and look at anomalies in some feed back info, when the condition occurs he can use freeze frame to look at inputs back in the shop. For starters I would fix the ABS just to get it out of the way.
