my mpg changed none when i removed the EGR... i did it because the long tubes didnt have the bung in the right place on them so i just capped it off all the stuff is still on there i havent had time to make a plate to block it off yet. so i can remove all that junk

 

I read an article awhile ago that made a good case for keeping the EGR on.

I searched and could not find it again, but one of the points was that the extra heat was useful in getting a complete burn of pump gasoline. Basically, the swill we buy at the pump has some components that require a high temp to burn. More complete burning of the fuel = more power and less emissions. Yeah, more heat is generated, but that's what you have a cooling system for.

The take home message was for a for a pump-gas, smog controlled street motor, the EGR is not hurting anything.

EGR got a bad rap in the '60s when performance enthusiasts detested newly required emissions equipment. But gas was better back then and cooling systems were usually worse.

 

Your check engine light blinding you lol - or did you have it knocked out via tune..???

If its eliminated thru tune , you can cap the EGR valve itself with a sprinkler 3/4 end stopper (it's the same size , aluminum caps work the best) - Then you off the DPFE, EVR and Pipe..

I got a pic of that , just not uploaded ..

 

I would love to get rid of all of the extra hardware under the hood.
Here's a reason not to-

haha long tubes increase exhaust flow reduces exhaust restriction which causes friction and increased heat so long tubes reduce exhaust temps in theory... which is why many properly tuned muscle cars still pass sniffers mine does. as long as the a/f comes out within the 14's while cruising u will pass a sniffer

 

haha even without it in the tune it never threw a CEL cause the EGR just sucked in under hood air. but the new tuner i got turn the EGR and rear 02's off i aint had my CEL come on since excessive idle code was thrown from me setting my idle screw higher. i turned it back down because it was hard to stop in traffic fighting the motor

 

Why clean up what you can't see.(at least not on my 98 F-150)

What sensors fail because of E.G.R.?

Not trying to cause trouble, just wondering why you would remove something that keeps combustion temps cooler, emissions down, prevents "Pinging"(witch can be very damaging) and actually improves mileage.

 

Well my 98 must be different because the EGR consists of -

The EGR valve, EVR, DPFE and frame assembly, EGR Pipe and hoses.. All that out of the way would be a blessing..

The sensor's ? Well count them yourself , I just listed them..

 

edit..

 

yeah same here, that junk is about 10lbs less I dont have hanging off my engine. I dont get detonation, I dont have any issues not having it.

 

Oh, You took off your plenum cover?

O.K. so one sensor is all I see listed.(D.P.F.E.)

Oh and built54, if your E.G.R. Valve etc... weighs 10 pounds you need your scale recalibrated. (Hope the wife hasn't been using it)

 

The plenum is under the intake manifold and wrapped in a rubber jacket - It sits on top of the block .. So , I don't know why that's even brought up.

All that stuff is an easy 10 lbs + prolly more with frame that holds the DPFE and EVR assembly. The 5.4L EGR valve weighs twice as much as the 4.6L EGR valve..

Theres 3 sensors listed and about 6 different fault codes you prevent from occuring.. I take that back , there not all exactly a sensor - rather, they can cause sensor faults.

 

It's an emissions control device, that automatically makes it evil, unnecessary, power robbing and communistic. It's The Man's way of holding the little guy down.

Or maybe it's something along the lines of, "I don't know what it is or how it works, so let's just get rid of it."

 

Don't get your undies in a bunch, sorry if I used the wrong tem, how is...... "Accelerator control splash shield" I didn't realize you cared so much. I know well that you are refering to the lower intake manifold not plenum but thats just another one of those parts w/ many names.

Anyway, nobody has given me a valid answer as to why remove an impotant device from your engine besides for cosmetic reasons and thats your own business. I merely was trying to understand why so many people think it's a good thing to do. I didn't want to get into a part name battle.

Thanks anyway.

 

That's right Quintin!!! HellIfIKnow what it does?? Exactly - I've seen dated explainations - Mines working perfectly - just replaced everything within the system..Taking know chances - have a 1900 mile trip ahead , soooo, yea..
