Im hoping maybe someone else has had this issue before and could give me any ideas into what i could look into. Pretty much its throttle response is really really SLOW I’ve already looked into everything throttle body related and maf sensor but everything seems good. And also when it go in the manual mode it will go down a gear on its own and it wont let me upshift so i put it on Drive and it changes gears again. Recently put a jdm engine and trans in it as well. Thank you for anyones input on what i could look at. OH and only CEL i have is for my o2 sensors cause i have test pipes on it
