It is Underneath the hood on the back wall it looks like a spinning top or a little pot with a lid. The EGR swich is right next to it. The back of the engine is the sparks plugs and it is above that on the back wall.

Take care.

05 uplander when i start the van runs fine, i go to drive have no power, throttle is spongy. when i hold the throttle to the floor it takes off with great power and then it runs fine from then on ,

For an EGR code, I would have looked at the EGR valve, wiring to it, and the catalytic converters first. The only other thing I can think of is the programming for PCM. I think you may have a wiring problem, keeping the EGR valve or throttle open. You need to find another shop to go to. You should complain to the shops you payed good money to, that didn't fix the problem. Get your money back. I'm not a point and guess car electrician. I get 2 hours to diagnose. 2 hours shop rate. I have a 95% success on fixing problems. The first time. The other 5% is major wiring issues.

Rough idle

the egr system works with vaccum and the vacuum control is a solenoid, who's controlling by open and close a electro valve,
if the valve is stoke open that allows the vacuum to go to the egr and make it work at the wrong time.

What will be wrong if I got code p0406 and p 404

both codes po406 and po404 refer to a fault in the EGR system
Po404 > Exhaust Gas Recirculation Circuit Range/Performance not within proper range.
Po406> Exhaust Gas Recirculation Sensor A Circuit High (meaning the circuit is open or disconnected)
Without actualy checking the voltages (wiring)
Replace the EGR valve
clear codes
test drive

Engine light came on and used my scanner and it came up with the code number of PO404.

po404 is telling the computer that the egr pintle is openwhen it shouldnt be, this sounds like a bad egr valve or carbon is holding it open, remove the valve and check for carbon, this is common on the 4.3 engine, if its carbon then run and rev engine with valve off, then reinstall valve and replace the gasket with an aftermarket gasket that was made for this problem, the new gasket has a screen to stop carbon from going into valve, here a picture of it.hope this is helpful.ab6f9e9.jpg974a1ec.jpg

Turned car off at gas station want start back acts like missin

all of these problem codes refer to EGR valve and emission controls. It may be, if egr was fixed, it would be ok!! take off EGR valve and clean carbon from egr hole in engine and from EGR valve. if egr valve is bad or plugged with carbon then the car will act like it is not getting fuel, it will bog down.
