Q: Engine power reduce

asked by on September 10, 2017

I have 07 Silverado, every time I turn on the A/c the truck goes to engine power reduce mode and loses the engine power. I need help because it keeps doing it more often now even though I keep off the A/c off it still goes to engine power reduce and traction control every 5 miles and I have to turn off the truck every time it does it !

My car has 143000 miles.
My car has an automatic transmission.
