Ok so my car heavily smokes Blue/whitish color ive heard this is my rings how much/time should it take to fix, i also have a p0402 code and i can hear my cat rattle so im guessing thats what that is(should i hollow it), also my tranny is greatly going from 1st to 2nd im thinking of doing a tranny flush and see if that helps, lastly when i first start my car and drive its very hesitandt like its dying then itll gain power rapidly then go back down but once i get driving that stops. PLEASE HELP THANK YOU FOR YOUR TIME
