Hi my name is john.
I take the air cleaner off and open the throttle body and look in at the bottom of the pleum to see if there oil in there.
the throttle postion sensor will cause the hesitation.
i just want to make sure it isn't full of oil.
I would clean the throttle body also at the same time when you replace the throttle postion sensor.
Let me know if you need more.
