Default sluggish accelaration

I have noticed that the acc has been quite sluggish. Took it to a local mechanics and he pointed out the engine sounding quite rough with a clicking sound. Showed me a simiolar rx300 and the eng noise was nite and day. Said it might bs a shifter in the valve. Any advice as well as recco on a good mechanic

It is a 2000 rx300

What year is your rx? It may be the sludging problem lexus had from 1999 to 2001.

Hard to tell without being there in person. When mine runs sluggish, I first pull the negative battery to reset the ECU, and then take it our for a spin. In addition, I take it you don't have a check engine light on the dash?

my acceleration is weird too. a few months ago I took my car to CarMax for a quote and the guy told me he saw oil sludge. now, I didnt take it to heart, because obviously he's trying to give me a crap price for the car...But after noticing how my car decel's nowadays, I think I may be encountering this problem. I need an oil change, I'm going to wait about 3 days until i hit 70k to take it to get an oil change.. but yea, if I find out I'm getting sludge, bye bye Alexis. I mean, I only have a 00 with 70k so..
