You're in the wrong section if you're talking about wastegate stuff. What happened before this? Did you do any mods? Check all your vac lines. Does it hesitate? Be more specific.

 

[david_chaney]

vac lines are all hooked up. no mods to the car. when the car is cold it dosent do the problem after it comes to temp its like when ur driving you will have to be more than half throttle to rev up other wise it boggs.

check your throttle position sensor voltage, it sounds like you have a spot of resistance.
