Hesitation at low RPM & Shaking at Idle
Hello,
I have researched and it seems everyone else has a more severe condition then I do.. The car Idles at the correct RPM but I feel it shaking a little... I know I have some bushing to be replaced so maybe that rules out that or maybe not.. But when I step on the gas it feels so slow until I get into a higher RMP and it shakes slightly. Once I am up in RPM the car runs great!
Any help on this one?

You have not said how long it has been since the plugs were replaced and if they have been then what type plugs.I had the same problem with my 1990 after I installed new plugs I found I had one bad plug,I bought the best pluds out there and in the end went back to stock denso plugs and the car runs great.PS only buy what the book calls for on lexus cars ox sensors must be from denso only everything else does not work right in lexus cars and I have been a machanic for 22 years,you would think I would know better then to use anything other then stock parts in my LS400 hope this works for you.I know just how crazy one can get trying to find the right answer to this type of problem.
I ordered some plugs today a long with some other tune up items.
