Thread: 00 grand Prix stutters when accelerator is pressed and depressed quickly...

I have a 00 gp non supercharged 3800. I never noticed this when driving the car. 125,000 No check engine lights

I sometimes rev the car up from the throttle from under hood to check for noises etc.

If I push the throttle and release it very quickly the engine will make a noise and stumble. It has never cut off completely though.

I was thinking maybe tps sensor...

That's the first thing I did... I will try and get a video of it though

Here's a video also, it only does it when I let it idle all the way down then hit the accelerator very fast.
