Ok so I have heard different things on the EGR tube going into the intake. I have heard of people deleting it. Which only makes your engine look cleaner, and makes a check engine light come on?

Now what about just rerouting the EGR tube to go out somewhere other than your intake, such as the side of the hood?

I live in the south, do I want these exhaust gasses going into my intake?

It’s hot enough outside

What’s everyone’s take on this?

 

you can reroute the egr tube. and youll get a check engine light.

the egr is there to scavenge unburned gas and put it back in the intake. thats what its supposed to do anyway.

 

That's not what it's for.

It's there to cycle inert exhaust gasses (already burned) back through the engine in order to lower combustion temperatures, reducing NOX emissions.

That it in a nutshell.

I always understood the the EGR was there to cycle inert exhaust gasses (already burned) back through the engine in order to help the fuel to vaporize better when the engine is cold. This will help the engine run smoother and reduse emmission due to un burned gas.

Most problems with dirty intakes is due to leaking valves. They should be replaced or cleaned time to time.

 

Listen to ProjectSHO, he is correct.
You cannot just alter the system or remove it because it is software driven and affects motor operation if not present.
1. a small amount of exhaust gas is metered back into the intake to cool combustion down during cruise conditions only. This reduces oxides of nitrogen emissions which is one of the 4 the OBDII controls.
2. when this action occurs, the fuel is cut back and ignition timing is advanced.
So, you can see what the interaction is between the hardware and the PCM software and what results there is likely to be.
Don't do it. It buys you nothing in performance and would lower fuel mileage.
The only time it operates is during cruise. Never at idle or heavy throttle applications or any other time except when the PCM is doing test routines..

 

Thanks for the replys all. I now have a better understanding. Guess i won't try to move it afterall.
