i have recently bought a 2002 kia and i feel that there are two problems with it
1) when i drive i can some what feel the engine and when the car stops at a red light it kind of vibrates ( not to strong to be a real problem but it's kind of anoying

2) i feel like its spends to much car for a four cylinder how can i check if it realy is four and if it is is there anytihing i can di to improve the mpg

thanks for your time and sorry i could dante but i bought car and am 19 therefore i am broke
