step on the accelerator causes car to shake

[-Regal-]

Hello,
I believe I am having the same issue. Control arm bushings were bad and was having an ABS issue with front left wheel. Changed control
arms, wheel bearings, quick struts, sway links, outer tie rods. Same shutter under acceleration. Thought it seemed to be drivers side and changed that CV. Still have a whine and shutter. I have the other axle and will put it in. wheel alignment when all are completed is on tap. Although the wheel seems to be straight and no pulling. Also will check motor and tranny mounts and recheck inner ties. seems loose on wet roads/ heavy rain.
No codes for spark issues. Still dealing with rear air ride issues. pain in the ***.

This is an old thread but I would unplug one ABS connector to turn the system off and see if it persists. If so, it's elsewhere. Don't overlook catalytic converter and muffler requiring replacement.

If you haven't changed the motor/transmission mounts I'd look into that because those tend to be the root cause of axles going bad, since a bad mount allows the transmission/motor to move too much which messes up the alignment of the axles to the transmission. At least that's what happened with me.
