Message i have the bad hesitation in my car. This past weekend I smoke tested my car and came up with 4 vacuum leaks. I pressurized the system from the drivers side boost solenoid vacuum line.( Im pretty sure that would pressurize the whole system?) Than i tightened everything up and fixed all the leaks.

I was driving and im pretty sure i heard the blow off valve go off when i was trying to accelerating heavy. 1/4 accelerates better than wide open throttle.

I ran codes with a snap on scan tool and got a tps circuit or sensor code. I checked the voltage and it was .34v and is supposed to be .4v at idle

also got a water temperature circuit or sensor code.
