Lexus RX 350 Throttle Body Cleaning 

The 2GR-FE is port injection only. Toyota didn't do any sort of direct injection until they created D-4S, their _twin_ injection strategy combining both port and direct injection. You can even see the plastic fuel rail running along the intake plenum going to the tiny plastic fuel injectors. These clearly are not going to handle the pressure of direct injection. While Toyota did add D-4S on the 2GR-FSE and 2GR-FKS, the second generation Lexus RX did not come with either of these engines, which is clearly the engine in your RX 350. Additionally, fuel injection does not affect how clean the throttle body nearly as much as it affects the intake valves. You may be confusing the throttle body dirtiness with the intake valves

U should use long wooden qtips

Also mark your vacuum lines with nail polish to prevent a mixup

I have a Venza same engine. It starts hard on cold start. The engine runs slower then normal till it warms up.

Did u have to take all those pieces out? Was hoping to c an easier solution. Thanks
