Mine was bad for a couple weeks before I realized what it was. My girlfriend hated driving in my car when it was acting up for this reason above. The looks I got from people......great write up here Britt.

Sure many people will use this thread. Thanks.....

Silly Question ! I have the 2000 DX 1.6 Auto Transmission. Do I have an EGR and is it located in the same place ? Forgive me. I just don't know. My car Rumbles a lot at Startup while still in Park. Was wondering if this could be my problem. Thanks guys.

you should see if your car has a small pipe coming out of the exhaust manifold and follow it. the egr is at the end of that pipe.
 
we have to reset PCM what is that and how do we set the pins sorry im pretty much new to all this






7. Reassembly is the reverse of removal. I suggest resetting the PCM while doing this, so the EGR can readjust after you start it.

8. You may want to follow the Manual's suggestion of measuring the resistance of the pins, but my car runs ten times better now, and I have no stalling issues anymore.

u dont even have to go this crazy. before u start working u should remove battery and press the brake do discharge any capacitors in the ecu. (it will also help u get your arm in there to turn the wrench) check engine light will go out within a few starts if your egr valve moves free after u reassemble.

does anyone's car chokes real bad to where it bogs down, and then jumps back up while at the same time accelerating by itself?
yes that was happening among other things when my egr valev crapped out. the rpms would not stay the same they kept dropping when engine was hot and when cold they were too high.

yup, I'm back at that stage.. I just cleaned my EGR 1k miles ago!! (argh)

maybe it's time to try out the new "revised unit". I'm sick of tearing apart my car in the middle of winter just to clean that valve haha

nah, at some point I got unsubscribed from the thread (probably when I deleted over 4k thread subscriptions). I'll go hunt down the post.

ya by buying and putting it in myself i saved like 300$ im thinking.
 
I gotta replace the battery in the P5. I might go ahead and attempt to clean all this stuff while I'm at it. Any words of wisdom? Heading out to get a state inspection now...before I f*ck anything up. Then as long as it isn't too cold out I'll get started on this...or maybe I should wait. I've got new spark plugs too. Yeah, I think I'll wait.

its not a comfortable thing to replace the egr valve so i would wait till you get check engine light and your engine idles like s*** before doing anything to it.
 
Yeah...but gas mileage has been down lately. I used to get 29-31 and the last few times I checked it was 26-28. I'll wait until the NEPOC guys can guide me through it.

gas milage is lower in winter anyway. they add ethanol to gas in winter plus u are running more accessories like lights and heat in winter. i wouldnt touch it. also check your airfilter. it gets clogged in winter from the salt on the ground and sand they spread. my egr went at 50200 miles approx. after my warranty was over. so it sucked that i had to fix it myself.
 
I'm at 76K and haven't touched it. I just replaced plugs, air filter, and installed a new battery today. I'll see how that goes. Mileage has been down for the past 3-6 months so perhaps it is winter but I'm thinking it is more likely my driving.

did u gap the plugs correctly? i cant remember what the gap supposed to be but the plugs are not usually gapped from the store. i got platinums in my car last summer and i had to gap them.
