alright this has been bugging me lately but whenever I SLIGHTLY rev the car (sitting inside) the whole car shakes, especially the steering wheel shakes vigorously like my car is some dragster race car... I also feel the hesitation just sitting down. I was told that it's supposed to be very smooth and you shouldn't feel much of anything on small revs (I was revving about to 2-3K and letting off, then thats when I felt all the hesitation when I let off the gas pedal).

I'm not sure what the fix is for this but I'm guessing it might have something to do with the Engine mount? Also, just another pet peeve is when I'm just driving whenever I step on the gas peddle and I immediately lift my foot off, I hear this very loud "THONK...." so I step on the gas peddle accelerate a little bit and I let off... THONK... What is this?? Thanks for any help guys! BTW My vehicle is a 1993 Lexus SC400.

the thonk could be your trottle body.. the butterfly closing. but im not sure its THAT loud.

as for the reving part. im having the same problem as well. only at 2k tho. if i rev at 2k the car would start shaking.. steering wheel shakes like mad.. you just hear the whole car shake. but if i go higher everything is fiine.. maybe the engine is resonating the interior? O_O'' who knows..

hopefully someone can help!

Your transmission mount is probably gone, and if that's gone I'd guess your engine mounts could use replacing too. Engine mounts might be a little complicated to get in there and fix without some kind of engine lift, not sure though. You should be able to get the tranny mount done yourself if you're a diy'er and you have a jack to support the tranny's weight.

Is your car bogging? if it is check your plugs, wires, etc.
