01 Slow acceleration. Help
Guys I got my father an 01 LS 430 a year ago. 177k miles, very well cared for car.
I took the car in to have the radiator replaced, drive the car around after and I noticed that its running very slow. Not like a 430 should be. I remember it being sluggish before on the highway so I decided to see whats up. I remmber my GS430 and LS400 being faster.
Basically it takes off fine but at 2500 and after its struggling. Smooth at idle and at high rpm. Occasional stumble/pop if I rev it in neutral.
I cleaned the TB and MAF. Filter is clean. Not CEL.
How can I know if the cats are clogged or if its a bad maf sensor.
What else can it be?
Thanks in advance.

Not sure. I have no records of it and none in Lexus database. Might have been done at and indy shop. Cant imagine them being factory original. Ill pull one out tomorrow to check.
Also, I realized after doing much reading that I only cleaned the temp sensor of the MAF sensor, I didnt spray inside the tube. Ran out of Maf cleaner and will have to repeat this again tomorrow.

found these on eBay. Are they this cheap now ?
I’ll clean mine again but perhaps having a spare new one won’t hurt ?
