I still suffer from slow or sluggish throttle response. I just had my I/C pump replaced by the dealer. I don't know... could it be my thermostat? It usually happens after I sit in traffic for a while or do some spirited driving. Is it just heat soak?

Any input would be appreciated.

Strange, that's classic cooler pump symptoms but with it just being replaced.

If you mean that when you push the throttle into the midrange, that nothing or very little happens. But that you get power at full throttle or part throttle, would could have a faulty throttle position sensor on the gas pedal or motor on the throttle body. I had this happen on my C32 where it had "dead spots" and if you were before or after them you got power, but in them, very little and what could be described as sluggish response.

Just reaching here to find you an answer that may be unusual and easy to overlook.
