Accelaration Hesitation

[chrisxr8]

have been having a few problems with my t lately. it started out at about 4000 rpm the car would start to hesitate and sound like it was missing but as of last week it started doing it even under light acceleration just above idle. I have changed fuel filter and plugs (they were white ) and when they scanned the car it said I had a throttle actuator fault. has any one else had to change out a throttle body with the same fault . any suggestions

I had dirty fuel and this caused the car to run lean on the std tune which then stuffed the plugs which then caused a miss and hence some hestitation. You have done the right thing to start with! TB is a common problem, try warranty?

would love to try warranty but its void. I forgot when the car is cold it runs nearly normal untill it gets some temp into it

Warranty will only be voided on areas affected by your modofications.

Throttle position sensor or actuator should still be covered.
