No EGR

[chevymaxx]

i took off my egr the other day, and made block off plates. what is going to happen if i run it without doing anything to the computer, like a simulator. will it screw my car up?

Re: No EGR

nah, might make it rich though (loss of 1 or more MPG)

Re: No EGR

Will it throw any codes with the egr not hooked up? I thought the sim was recomended so it didn't throw codes.

Re: No EGR

took mine off and it threw a code

Did it affect driveability at all?

Re: No EGR

My car has like 3 codes right now, all of which I know about and planned for. As long as you don't mind running a little rich, or mind the SES light on, don't worry about it. Think about it this way... if you put a flamethrower kit on, it'd just be that much more epic.

You should worry if your state has emissions checks though.

Re: No EGR

seemed to run fine

Re: No EGR

will throw a code. I deleted mine and then got rid of the code with hp tuners. Runs just as good as before

Re: No EGR

if u delete that code, will gas mileage go back up to normal? i thought the lower intake temp helped gas mileage, but i'm just a n00b

Re: No EGR

running to rich will plug your cat so if you smell gas out the exhaust id unplug it your also probably loosing some timing the recirculating exhaust gas helps to cool the combustion allowing more timing

Re: No EGR

and on a 3.4 atleast 95 you can just unplug the electrical connection for the egr no need for blocking plates

Re: No EGR

the egr doesn't lower intake temp, instead it fills the cylinders with COx (think that is what it is called) which takes up spaces and helps burn all the gas and air mixture. Exhaust is hotter than incoming air into the intake. Removing the egr actually lowered my engine temps by 6-8*.

Re: No EGR

i agree that no egr lowers intake temps and like you said it does fill the combustion chamber with a gas but since its already burnt it doesnt burn again making the temp of the combustion chamber cooler because of a smaller fire i believe it will make a little more power all im saying is you going to loose a little timing i guess there really wasnt a point

If you have problem with your car and will pull engine light bulb out would your car be automatically fixed?

If you are looking for gas mileage - do Not touch it. You will loose 1MPG if not more and you wouldnt gain any power. If this is good deal - go ahead and do it.
Will throw about 3+ different codes in a while.

i really dont think so, to both
it will make a little more power at WOT if you dont have the EGR
and it will stop putting all that carbon/heat in the intakes
