some people have this problem some people dont

but the problem is only when the car is really hot, then you have to give it a lil gas and it starts right up. if the car is stalling then thats a whole diff problem and not the utec

its nothing major and you will get used to it

i dont even notice it anymore

but if you dont currently own a utec, then do it right from the get go and get a haltech, unless you have someone that can tune a VPRO near by
