The egr valve only operates in a modern system when the vehicle is not at operating temperature to reduces harmful emissions.

You will noticed no difference in terms of fuel economy without an egr valve

I deleted the egr valve on my camaro because it restricted air flow into the intake manifold, in the ls1 the inlet tube protrudes significantly into the intake manifold. The car is not stock, I have hptuners for aftermarket tuning and I have the knowledge and tools to make sure the car operates correctly and passes emissions testing

Pro:
My camaro's intake manifold and heads are clean as a whistle
No exhaust or intake circulation restrictions

Cons:
Your car will not pass emissions testing
You are now solely in charge of your vehicles maintenance. Any issues that arise even un related will be blamed on your modification
The next owner will have no idea what an egr is or does

Your answer: retain all factory vehicle components unless you perform all of your own maintenance and up keep.

I hate fords, everything on those rangers and explorers was controlled with vacuum lines and tubing. Be happy your ranger is running correctly, don't add to your possible maintenance problems on a daily driver
