EGR delete guide for 3.2L/3.5L
3.5L engines, EGR systems were incorporated to decrease emissions and increase gas mileage. The system was deemed unnecessary and it did not show up on later model engines.
The EGR works by expelling exhaust gases into the back of the upper intake manifold. This hurts performance for three reasons. First, it decreases the amount of fresh air entering the engine. Second, it increases the temperature of the air charge, and three, it adds crudded up junk to the intake. You can see this if you have ever removed your intake plenum.
This system can be disabled without throwing a code.
1. Remove the plenum
2. Cut a section of tubing on both sides going from the EGR solenoid to the plenum
3. Cap all four open tubes
3. Cap all four ends
This is a schematic of the EGR system taken from the FSM.
This picture shows the severed and capped EGR tube coming out of the driver's side of the plenum.
Just below the fuel line and heater hose you can see the EGR tube. It is capped and hose clamps on both ends.
This is a picture from the passenger side of the vehicle. It shows the capped EGR tube. On the extreme left side of the picture you can see the EGR valve itself and the metal tube which connects the EGR valve to the EGR tube.
