around 50 mph, there is a knocking problem

04-05-02, 04:52 PM

when i lay off the gas pedal at 50 mph, and then gradually begin to push the accelerator, there is a severe hesitation, and almost a knocking feeling. just wondering if anyone else had this problem. the dealer said this is normal, but it felt far from normal. the car is a 98 vette and has about 60,000 miles on it . thanks a lot for any help.

with that many miles i would clean the throttle body as it may be carboned up.

Hi there,
First, if I may, I have a few questions please.
In what gear is your transmission???
Are you on a flat surface????
Do you ever get the check engine light???
What service work have you had done recently, within the last 15000 miles?
Let us know, and we can proceed, c4c5

HI there,
Following the information given to me, by your PM, I would say that maybe you have an issue with your transmission, and the torque converter clutch.
While I am not sure, I would say that this would be your starting point.
To check this, is very difficult, and would require some time.
Please keep us posted on how you make out, besttoyou, c4c5
