Re: Hesitating throttle,

With INPA you should be able to check the yaw sensor.

Re: where is the sensor that reads vacuum ?

Re: where is the sensor that reads vacuum ?

Why do you need to know vacuum?
The MAF gives the mass of air going in and the ECU controls the fuel going in through the injectors and then gets feedback from the lambda sensor(s) to tweak the fuelling accordingly.
