thats what i was thinking also since it was an EGR code, so you think that when i remove my EGR the problem should dissappear. and if anything changing the fuel filter and cleaning the fuel injectors wont be hard at all. where is the EGR valve anyways???

The EGR valve is bolted to your passenger side cylinder head, right up front at the top of the motor. Two lines come out of the bottom of the valve, one draws exhaust from the passenger side manifold and the other passes that exhaust to the top front of the intake (just behind the throttle body). The black cylinder on top of/between those two lines is the valve, and it controls how much (and when) exhaust is released into the intake charge.

has anyone else had this problem with the EGR?? i mean i know where all the EGR stuff is but i just thought it was a valve like the AIR check valves, so just remove it when i do the header install and it should clear up the problem? and does the egr have any fuses or anything like that b/c i am gonna get it tuned the weekend after the install so my rear O2s and all that stuff will be removed and gone. and also can i just go to autozone and buy the freeze plug for the top of the manifold??
Egr This sounds like the problem I'm having now.
My car has been stalling when I driving the idle will drop down to about 500rpm and then sometimes it will pick up to about 800rpm and be ok.
Sometimes it stalls and the motor dies this is very danderous as the power steering stops working and the steering goes really heavy.
Quite often I am turnig a corner or negoiating a roundabout at the time so it's driving me nuts. ( lots of roundabouts in the UK)
Anyway I scanned the car and I'm getting a P0405 code which is EGR sensor low voltage. everytime I clear the code the next day it's back.
If I shift into nuetral I can restart the car and carry on driving but the other day it pushed me out really wide on a rounabout and I almost hit another car.
Does anyone have a part number for the EGR valve and a rough cost?
Or can I take the EGR valve apart and clean it?

i believe speed inc sells them, i just put in my headers and finishing up the Y pipe today and taking her out for a spin couldnt last night bc of snow and icy roads. but i started her up with open headers and damn she is loud lol and should produce some major power when i reved her up the RPMs went up alot faster than they use to so i cant wait to see what she can do on the road today lol.

GM list is something like $180 for the part. Places like GM Parts Direct sell it for about $110 shipped.
You will probably also want a new gasket with the valve. That part number is 12558353, and it lists for about $7.
I don't think there is anything you can do to clean the valve. Either replace it, or remove the EGR system. If you remove it, you'll need to get a block-off plate for the hole it leaves in the exhaust manifold, and a plug for the hole in the intake.
Egr Thanks for that, I took the EGR off today to check it and it operates ok when I push the valve open with a screw driver and it's spring loaded and appears to close ok.
$110 sounds like it's cheaper to block it off.
What would happen if I just disconnected the EGR valve by pulling the plug on top of the valve.
I would throw an SES light but would the car run ok?
Cause this stalling out is dangerous it only happens when the car is warm
Sorry Z28LS1Camaroguy for Hi jacking your thread good luck with your new header trials.
The roads are really greasy in the uk too it's impossible to put any real power down.
Cheers Andy

Guess the best bet would be to remove and block off the whole system if you don't want to pay for a new valve. Again, this is assuimg that your issue is actually due to EGR problems. Lots of things can cause stalling/idle issues. Maybe try doing a search on this site under "idle" in the External Engine, PCM/Dianostics, and General Maintainence forums. I know quite a few threads have discussed in depth possibile causes for idle issues.

Egr Hey I tried something today I disconnected the EGR valve, just pulled the electrical connection out the top.
The car ran great, I threw an SES light code p0405 again but I expected that.
My Tach needle stayed as it should when coasting to a halt no more revs dropping below 500rpm and stalling.
So thats what it is bad EGR valve, I have just bought a second hand one from a kind person on here who PM me.

well i got my headers and offroad Y in and it sounds great, new plugs and deleted EGR and AIR it feels like it pulls alot better and smoother. also the idle is still kind of low but doesnt die down when i shift from park to drive anymore so i guess when i get it tuned this weekend i will just see if they can adjust the idle.
Egr I have been driving the car with the EGR valve unplugged for a couple of weeks and the car has run fine no stalling, gives an SES light and a P0405 code.
My secondhand EGR valve arrived frm the USA today and it took 2 minutes to swap them over. I reset the SES light using my laptop and the car runs fine no stalling or SES light.
So if you have an SES light which throws a P0405 code just change the EGR valve.
I got mine by placing a want ad on here there are plenty out there as a lot of people remove them and blank them off, I was offered three.
