Hello, I would like to know if there are any guys out there that have the same problem I am having. Is there any sensors that can make the car hesitate or have a flat spot at high RPM, it does not do it all the time but during the day when it is a bit warm it does it at night when it is a bit cooler it does not do it, that is why I think it is some sensor. I checked it for the leak on the intake manifold but it is not lealikg to the extent the dealer claims, what should be my next move???
