I have a 93 ls400, and lately its been having a light but noticeable vibration feeling in the gas pedal, kind of like a stutter or cutting back type feeling, but the rpms don't fall or jump, stays smooth. I don't feel it during idle, really only when I'm maintaining speeds around 45ish and 60ish mostly. Any ideas on where to start checking for issues?

Miles on car? Vibration only through the gas pedal?

DertyDOH

161,000. I can feel it slightly in the floor with my other foot, but not the steering wheel or anything

I say engine mounts. I had some vibrations like that on highway. Changed the mounts world of difference.

guess I'll start looking into the mounts, how much did it cost you?

I got oem from sewell cost was about 100 a piece. Since you need two of them. You can either put them in your self or pay a garage to do it. Either way you go worth the investment. Just make sure all other suspension,brake, and tire issues have been checked first.

Throttle linkage maybe?
