2005 Cadillac SRX
 

My SRX showed the traction control light came on. When ignition was turned off and then turned back on I got a signal that said "engine power reduced". The car would barely run at less than an idle. I took it to the dealer and they replaced the power throttle control and two days the exact same thing has happened again. First the traction control light comes on then you get the engine power reduced. Any ideas??????
