Carbon Buildup = Fuel Injection Flush??? - Toyota Yaris Forums

ok, thanks guys. One thing i forgot to mention is that is it automatic transmission. I am a bit confused about all this, as there are different answers.

However, I am guessing the Brake Fluid might not be bad because of the ABS (but it is not in the maintenance manual, so i wasnt 100% sure, and I am a newb). Still waiting to hear more responses. Now, it looked complicated doing it myself from what i have seen in pictures / videos, but will relook at that and see if i can find it for a yaris. Anyways, the 100$ brake fluid is not that huge.

However, what is huge is the Fluid Injector Flush and the Throtling Body Service. They say there is carbon buildup and it is recommended i flush these out and do the maintenance at 89,000 km. I know Jambo101 said i dont need it. Would like to hear a bit more on this subject, and why i dont need or why do i need it. What is this issue anyways. Again, I have never started using additives yet to my fuel (some say it is good, others say it is bad), and dont know if this will remove the carbon build-up, and i dont even know if carbon build-up is serious and needs to be addressed quickly. Again, would appreciate your thoughts and detailed reasoning. Has anybody been told this by the dealer / mecahnic before?
