morning hesitation on 02 santa fe
 

hi guys,

I have an 02 santa fe with about 90k miles on it that has developed a morning hesitation. I thought the problems were the plugs and i had them replace with Ngk platinums but the problem still persist. Once the car warms up is fine all day again it only has this issue in the morning.

does anyone have any ideas of what the problem is?

all your help is greatly appreciated.

ps. no check engine light
