Question Car porpoises when I hit the gas

Sometimes when I hit the gas about 1/4-1/2 throttle from a slow roll the car porpoises. The car goes fast, slow, fast, slow making it very difficult to stay even on the throttle so I have to let off the gas completely to get it under control. Is this just my foot or is the car acting strange?

I've noticed this is most pronounced when the car is just warmed up.

I'm no car expert, but is traction control on or off? Does it do it in both? The '01 Mustang I had would do the same thing with traction control on. Turn it off and it was fine.

TT is on. I also noticed it did this once when I hit the gas after going over a speed bump.

Try it with it off. This may be a normal function. Were the roads wet when you hit the gas? I'm not trying to get you spinning off the road, lol, just troubleshooting. Might have some luck in this forum. They talk about similar issues with Stabilitrack.

that's the 'bouncy bounce' of not enough gas...like you did when you first learned to drive a stick. It's touchier in this car...

Try giving it just a smidge more gas...it'll settle down.

Shift to 2nd gear. Also sounds like your'e sitting up in your seat. Put your seat closer to the pedals and stay back in the seat.
