My car's been having this issue for a while now, but unless the car's already in motion, like say stopped at a light before an uphill grade (approximately a 15 degree grade), it will shudder when you put a large amount of throttle and lose power. Earlier today, the car was only going 35 up the bridge (55 was the limit) and shuddered until I reached the level road on top. The check engine light did come on, but it turns off as soon as the car recovers on the top. I had the pedal down about 3/4 of the way and the RPMs stayed just above 2500rpm, I could easily feel the car holding back and shuddering slightly. It only seems to do this if I'm not already in motion, as there is a hill I drive up when leaving the college I attend, the car doesn't shutter, but it does feel weak. It also experiences this from a stand still on level ground but only if you put a good amount of throttle (about more than half-way on the pedal). Otherwise, the engine works fine, but doesn't like high throttle input when in motion (like for passing).

I searched into this and I got a few things saying it's the engine mounts (specifically the CV joints and half shafts, though this was for a '95 Intrepid), so I wanted to make sure before I decide what the issue is.

Welcome to DF
My first guess would be an o2 sensor, That will cause the ck engine to come on and go off.Have car scan for any stored codes.

 

We checked for codes and none were popping up.

 

Replaced the spark plugs and according to a family member who drove the car today, it's running like normal now.
