Only on the 3.5L and the 2.0L. The 2.5L is a pure direct injection without port injectors regardless of what revision was made to the 4gr-fse.

Lexus did not discontinue the 200t engine. The IS/GS/RC/NX300 are all the 200t (with the exception of the AWD cars).

Great advice! I notice even on my personal cars, if I just put put back and forth and don't open it up, they don't run as nice. Some of you will remember, Ford was having a similar issue on early ecoboost V6s, specifically in Explorers in colder states but not as commonly in F-150s and cars in states that don't have a real winter. They could not figure out why it was effecting Explorers and not the trucks, and what was causing so much carbon build up on the valves they would in extreme cases misfire. Well, most of the Ecoboost testing was hard core, wide open throttle abuse and they never did any long term testing of overtly gentle use, as with any if not all manufacturers. Basically the average Explorer driver was just creeping over to the store, dropping the kids off, and going through short and very gentle trips, while the F-150s were getting driver significantly harder. These cars were in cold environments and on short gentle drives were commonly not even reaching operating temp. Durability testing for cars in most cases consists of trying to simulate years of hard abuse in a short period of time, which does not test the conditions of the gentle driver. I imagine it is no different for Lexus in this case. Long story short DRIVE YOUR CARS HARD PEOPLE.
Ive talked about this in 2nd Gen IS forum 2 years ago ! the only way to get 99% carbon issue fix is BUY an IS350 .

Of course there are other models that were AWD before that such as the GS300 with the 3GR-FSE and the IS250 AWD with the 4GR-FSE, but they are not related to what was being discussed relating to the renaming of the 200t to the 300 for RWD models.

My point was that between 2017 and 2018, the 200t became the 300 and the AWD models didn't change. The 300 AWD was a detuned 2GR-FSE in 2017 and it still is in 2018.

Remember that the 2IS ran for 8 model years (2006 - 2013). Hopefully they don't let the 3IS go as long, but if they do, that would mean we won't see a new model until 2022 (3IS from 2014 - 2021).

Gives them time this Gen to throw that new twin turbo 3.5 in the car and call it an IS-F.
