In the morning when I first start, the car idles fairly rough and the needle goes all over the place. When I go uphill or acceleate, it knocks slightly. I cleaned the throttle body about 6k ago. Could there be a problem with the air flow sensor or a vaccuume leak? or maybe something wrong with the gas flow or timing?

Last night I changed my trans fluid. Used Dex III which the guy at hte parts store recommended. But this morning I was looking around and nowhere could I find any suggestions to use Dex III. One place suggested using Mercon III. Could I have made a mistake?


I also swapped out the radiator about a week ago. There seems to be a difference in the level of fluid when its on vs off. Should I be filling it to max then its on or off or should there be a difference? there seems to be a bit of pressure inside when the cap is taken off.
