I have been having an issue of my 2010 Nissan Marano feeling like it’s losing power and then it takes off like normal. Recently I had the transmission fluid changed and they check the wiring and the battery and all that was good. Now I’m getting a P0011 and a P0021 coming up. I checked the oil it wasn’t low but it’s probably due to be changed. Any ideas why it just randomly feels like it loses power for a second or two upon exceleration And then it takes off and runs like normal.
