Re: Egr ??????????
You'll still get the code. The fact that you're getting a code with an EGR means that it isn't operating right. Whether the valve has crapped out, a vacuum line feeding the EGR or the solenoid is broken / disconnected, or the solenoid itself is junk needs to be determined. If you unplug and remove the solenoid, then remove the vacuum lines to/from the solenoid, remove the EGR, plug off the end of the vacuum line that used to feed the solenoid, and just toss a block-off plate on it, you'll still get the Check Engine light and the code.
The light for EGR issues will normally come on at cruising speed; interstate or good 55mph cruising. The optimal fix is to remove the EGR system and have one of the chip burners on this site burn a PROM for you that has the EGR error deleted out of it so it'll never come on again.
Mine does the same thing on the highway, but I have the plate. A custom chip is on my "to get" list.

Re: Egr ??????????
Disabling the EGR is one of several features that make the Ultimate chip such a worthwhile investment...

Re: Egr ??????????
Deleting the EGR will not cause any harm to your motor as EGR stands for Exhaust Gas Recirculation. Basically exhaust gas is re-routed back into the combustion chamber because the exhausted air is much hotter than the intake air (this kind of raises your intake temps a bit lol). The whole theory behind the EGR as I understand it is to reduce Oxides of Nitrogen (NOx). Undernormal combustion, Nitrogen(N2)Oxygen (O2) in the air and Hydrocarbons (HC) in the fuel combind into water(H2O) Carbon dioxide (CO2) and the Nitrogen remains unchanged. Under very hot combustion temperatures, the Nitrogen reacts with the other two byproducts and forms Nitrogen oxide (NO). After being released into the atmosphere, it picks up another Oxygen and becomes Nitrogen dioxide (NO2). In the presence of sunlight,
it combines with other compounds like Hydrocarbons and forms Smog. Since exhaust gas is inert (very stable) it doesn’t burn again. So by being introduced into
the combustion chamber, it will lower combustion chamber temps enough so that
the Nitrogen doesn’t react with the other compounds and is passed unchanged out
the tailpipe thus not contributing to smog. Now, since exhaust gas doesn’t burn, it
doesn’t exactly help with combustion. At higher RPM’s, this really isn’t noticable,
but at idle, the reintroduction of exhaust gas will cause a very rough idle and can
cause stalling if to much is introduced into the combustion chamber
In other words I have deleted mine and enjoy the lower intake temps

Re: Egr ??????????
you are now banned again, since you were previously banned once before for insulting another member here in this thread which was unprovoked and completely uncalled for.
you are no longer welcome on this site. take care.

Re: Egr ??????????
wow, how did this happen. is this screen name different than a previos name he had? why would he get banned, i didn't see any insulting going on.

Re: Egr ??????????
He also so kindly signed his post in the other thread with "go big or go home", which was what his new screen names user title was until he was banned, this guy is obviously a sharp one.
as for the insult,
end of story. this topic is finished, any further posts reguarding this will be removed. thank you.
yes, the screen names are different, he so nicely added a "_" to this name, but the rest is the same.QUICK STORM said:

as for the insult,
is a direct bash/insult on user sytyguy, which was doing nothing but offering help and some advice.
