well it is a bunch of issues in my 2000 Kia Sephia
When car is stoped at a red light it shakes or sputterers.
the gas mileage is horrible what increases and keeps gas mileage in a kia sephia besides oil change, and do u know what could cause it to go down quicker.
When i get another oil change could i use 10w-30 instead of 5w-30 would that help the engine since the car has over 170k miles on it?
If i had my automatic transmisson fluid changed would it stop some stalling in acceleration and make it easier for gears to change. I just had it replaced in jan. or feb 10. but it took them 3 transmissons to get one to work so i dont know if they just put that one in there cause it worked. im just trying to avoid buying another one.
If you could help me please!!!
