Hi and thanks for using 2CarPros.
The throttle body is located at the front of the upper intake manifold. See picture 1. Some have two bolts others three bolts holding them in place. If you follow the air box induction tube to the engine, it stops at the throttle body.
Now, the reason you cannot find this online is because it is not recommended. Take a look through this.
2. Fuel Injection (Induction) Cleaning / Flushing:
This is not a Kia recommended or required maintenance procedure. Targeted cleaning should be used if, due to unusual circumstances, the system has found to be contaminated. If a vehicle is experiencing fuel system contamination it should be diagnosed and repaired following factory recommended procedures. Reefer to TSB Fuel 010 for Throttle Body Cleaning. For instances where the Kia recommended fuel (a TOP TIER Detergent Gasoline) is not available/not used, see information about Kia's recommended fuel additive in TSB Fuel 022 and below:
"TECHRON(R) Concentrate Plus Fuel System Cleaner" is now Kia-approved and recommended for complete fuel system cleaning during routine service intervals as preventative maintenance (for late model vehicles, refer the vehicle owner to the maintenance section of the owners manual). A 12-ounce bottle will safely treat up to 12 gallons of gasoline, and can be used in all gasoline engine types, including MPI or GDI systems. TECHRON(R) Concentrate Plus Fuel System Cleaner should be used at every standard oil change interval (7500) miles, if TOP TIER detergent gasoline is not available. TECHRON(R) Concentrate Plus Fuel System Cleaner effectively cleans fuel injectors, intake valves, combustion chambers, and protects critical fuel system components from corrosion and sulfur content in fuel. This product will not harm emission control systems and will not leave behind harmful combustion chamber deposits.
If you noticed, they recommend a product, TECHRON(R) Concentrate Plus Fuel System Cleaner, as what should be used to clean the entire system. That would include the induction and injectors.
As far as the EGR, it does not have one.
I wish I had better information for you, but this is the bottom line.
Let me know if this helps.
