@steve65417 exactly what happens? Include RPM's etc. while you tell us the history and explain the current issue a bit better. What is the exact engine size and what have you already checked? Have you gotten the OBDII scanned yet? Any codes popping up?

There is a hesitation in the gas petal.

4.2 liter in line six 2008 trailblazer.

When this happens the traction control light comes on the dash.

It acts as if the traction control is on.

I googled the problem and it said to maybe replace throttle body?
