Engine jerking around with AC on

I have Acura TLX 2018, Tech package. Not AWD. I only have 11,000 miles on it, pretty new. Recently, i am noticing engine is jerking around when i push on the Accelerator. and this seem to be happening with AC on most of the time. What do i mean by jerking around ? i mean like huffing and puffing,, No unusual noise though, and No check engine lights or other warning lights on the dash board. What could this be ? Did water get into the engine ? there had been some big storms lately in my area on and off for weeks. And my car was parked outside. I just changed my oil and service guys didn't say anything ... and i forgot to mention this to them....
