Was taking a 2 hour drive today.
After I went to the off ramp I downshifted to prepare to merge and speed back up.
I had the proper rpms for the gear. After I started accelerating the car bucked and then caught back up and continued normally.
It's happened going to a near stop at a stop sign and began onto the next road and then wen back to normal after it bucks.
Anyone have any idea why it would do this?

There's a TSB regarding air bubbles forming in the fuel pump after an extended cruise at steady-state speeds resulting on hesitation/bucking when you try to accelerate immediately following the cruise. We had the issue with our '06 Pony. If that's it, replace the pump.

Also, the TCS will inhibit spark/fuel in some cases under heavy acceleration.

Ahh. Sounds about right. An hour + at 80 may do that
Since warranty would be out it wouldn't be covered would it?

Edit:
It wasn't that heavy accel. It did it just doing light takeoff on an off ramp stop sign

If that was the only occurrence then I'd write it off as an anomaly, maybe fuel related, and just pay attention for future occurrences. The throttle body on the S197 tends to gunk up pretty quickly and will cause some idle and performance issues so I'd clean that and replace the fuel filter. Many folks began having issues with fuel filter clogging by 30k-40k miles.

Well it's happened 2 times today.
Once last time I made the trip.
I don't usually take 2 hour continous trips so isn't high on my list of gotta do's.
Atleast I know of possibilities incase it begins happening more.

One question. Car does this. Brother tripped it 3 times today when I let him drive.
Engine wen to limp home mode with the little wrench lit up
Is there a way to deactivate this?
I assume there is since it would hinder racing.
Would taking it off cause any damage under said heavy acceleration or is it more of a safety issue?

Pressing the TCS button (next to the hazard switch) will deactivate it. First time I downshifted to pass a car on the hwy at 70mph and it did this scared the crap out of me... Learned real quick that I always press the button when I start the car unless it is nasty/wet outside. Now I can downshift and gun the accelerator with no worries. No problems doing this.

Well i took it by the shop to have my codes scanned. turned out to be p2104 and p2111.
Uncle said it was the TB and whenever I could let go of it to bring it by to look at. Will be dropping it off tomorrow morning.
