I have a 2002 when driving a steady speed the car seems to cut back on power as if you downshift. The RPM's seem to stay in the same spot but the car feels as if someone is pulling it back. Anyone ever seen this???

 

Is the problem reproducable? If so, have you tried reproducing it with the VSC turned off?

The VSC has the "power" to cut the throttle back, if it senses this is necessary.

My second thought would be harder to troubleshoot...the throttle position sensor. It's a mechanical component with an electronic output (telling the computer how hard you're pressing down on the gas pedal).

 

Thanks I will check the VSC. If not is the throttle sesor hard to replace?
