Throttle body. To clean or not?
Hi Wato, what can I say your incredibly lucky or its a testament to the Lexus legendary build quality. With my Maxima at a standstill the revs were so high it was "pushing" the car forward, which you don't want to deal with ever. Regards. -

Throttle body. To clean or not?
Well Ashley lol no I didnt clean the throttle body at all! There wasn't enough info out there or stories about someone doing it to make me feel confident I wasn't going to cause damage. Its a similar problem with nb Mazda mx5's. They have that coating on the flap as well and I actually scrubbed that off before I read no, don't scrub that off. But for some reason the idle came down slowly when I pushed the clutch in then after a few k's it fixed itself and runs great again. The Lexus is running a treat now so im leaving the throttle alone. Thou I did clean the MAF sensor a short while back and that made a big difference. Cheers! -

High performance LED headlight globe for 2023 NX350H
The brightness of the original LED headlight globes in my 2023 NX350H Luxury base model are so poor that it borders on being dangerous to drive at night. Any suggestions on suitable LED replacement globes to significantly improve the brightness would be greatly appreciated. Jeffrey -

Throttle body. To clean or not?
Hi guys I saw this thread title and immediately thought " I hope he hasn't done it yet". I decided ( god only knows why) to clean my throttle body on my 05' Nissan Maxima ( yes I know not a Lexus), and all I accomplished was destroying the throttle body butterfly fly by wire leaving a gap so it revved close to 2K rpm at idle. To pile on the pain I also decided to "clean" the metal surface on the body itself, massive mistake as all I did was rub off the factory coating ( slightly rough coating before the butterfly). I sincerely hope you haven't done it yet because its a irreversible action especially if you push the butterfly, now I'm assuming Lexus use fly by wire on their throttle bodies but I may be wrong. Best regards Ashley. -

U0101: Lost Communication with TCM on ISF
Hi AUISF33 did you end up fixing your problem? I have almost the same problem. ABS, Power steering & the seat light are all permanently on. Temp gauge doesn’t work, clunky in manual mode and is in limp mode. Checked all the fuses, battery is getting enough voltage, checked all the OBD wires with multimeter all good. Pulled out the ECU to see if anything was faulty and cleaned all the electrical connectors and still no good. Got an auto electrician to have a look and he said not getting any signal from my ABS module that’s why can’t communicate with ECU. He said he needed wiring diagram for the ECU, ABS & Power steering which I got and sent to him but hasn’t returned my calls. Not sure where to go from here, do I get a new ABS module and hopefully fixes my problem? Don’t want to take it to the deal shop cause they will sting me. Would like to fix it myself if I can.
