Decarbonization & Throttle Cleaning
Hi,
I went to Lexus today for my first oil change. While there they suggested I also have the fuel system cleaned, engine decarbonization and a brake fluid system flush and replacement. All of which I agreed to. When talking to the representative afterwards she said this was normal wear & tear and nothing I can do to prevent this in the future. Should I expect to do this everytime I need an oil change?
TIA

No, i wouldnt expect these services to be performed at every oil change. Typically brake fluid is every 30k miles. I would suggest the fuel system and decarb every 30k as well. So no, these are services you may have needed today, but wont need again for a while.

You didn't post which Lexus you own, but it should be the same for all.
Carbon build-up is just going to happen, not much to stop it except drive it like you stole it! lol
Throttle body cleaning is quite simple, and takes 15 minutes. Hopefully they didn't charge you like crazy to do that. Clean the throttle body every 2-3 years, just to ensure better mpg, and good throttle response.
You can put in a can of fuel injector cleaner about every other oil change, if you want.

DRIVE THE SNOT out of the car for 10 minutes or so. Obey your local laws, but your car will need to be driven as hard as your local limits allow, and likely harder than you have probably ever driven it before. Floor it everywhere, high revs...You have to get the cats good and hot to burn out all the crap you just put through them. Failure to do this could result in burning up your catalytic converters ($800 a piece).
This will (more or less) do the exact same thing as the Engine Decarbonization process they use, for $10. If you do not feel comfortable doing this, this is likely the same treatment you get at the dealership, only I would hope they would not drive your car afterwards. They can do it in the shop just revving the engine, and can adjust things via a MODUS system to change the way your engine is running, and watch it closely so they do not damage anything.

hmm speaking of which i was thinking of putting a good quality fuel injector cleaner. my car has like 105,000miles on it and i have had some bad start problems. some times the car just wouldnt start and i have to give gas and after a min or so its working and idling all fine. its just @ start ups.
i cleaned the throttle body, MAF sensor. i will be changing the spark plugs. maybe that might resolve the issue.but in meanttime i m thinking of puttting fuel injector cleaner and see if that helps

ya i did checked the thread but i IACV sensor that is held with 2 screws is messed up. One of screw head is gone and the groove is messed up. So now i cannot remove them @ all. but i did clean in and around the intakes.This is what happened to it. Now i am a bit hesitant on using the extractor tools since that thing is a sensor.

ya thats true too..but i followed the instructions thta Lexmex had posted under Rx300 forum on hoe to clean it. But in anycase i managed to remove those bad screws and cleaned the **** that was inside. So now the car starts perfectly. if however it doesnt start down the road then ya i will have to remove that entire unit. that is pain in *** to remove that whole thing tho.
