2010 CHEVY MALIBU 2.4 LITER 4-CYLINDER PROBLEM

[GUEST SUZY]

as I start the car it either shakes along with if I step on the gas pedal it still dont accelerate and if I stop or slow down it shuts off. Or as I start the car it also sometimes accelerates really high on it's own and it jerks to switch gears. once I put it in drive it just goes on it's own. I'm clueless as to what it could be especially because I'm getting all kinds of different codes almost everyday. it keeps telling me engine power reduced. help

what are the codes that you are getting?
