1fast5.0 · October 29th, 2008, 09:08 PM

what do i need to do after deleting egr im in the process of switching to a carb but im waiting on some money for the manifold and i need to know how to get it to run semi right please help

WildWill · October 29th, 2008, 09:23 PM

is it pinging? or will it just not run?

1fast5.0 · October 30th, 2008, 02:26 PM

there is no pinging but it studders like it not gettin enough gas and after sitting still the idle start surging

So, what did you do with the vacuum lines going to the EGR valve? I think there is a red one and green one(can't remember) They should run to your valve, under your upper intake and to other lines on the passenger side. If you haven't gotten rid of them, do it or at least cap them off. I deleted my EGR and didn't have any of the problems you are having, I also deleted it in the tune.

i have all lines caped that should be it just feels really sluggish since i removed it and i deleted my smog so i dunno it want be a problem in a couple of months when i through the carb on it it will be a pure beast the efi is way to much trouble to deal with and the computer i need none of it i want a pure motor no electornical tuning and thats what i will have soon enough

LOL! Yeah, a carb will really wake her up. That's some funny shit right there.

Why did you "delete" your EGR? It didn't help your performance at all (obviously). The obvious solution is to "undelete" it.

95opal · October 30th, 2008, 07:28 PM

Are you still running a catted h-pipe? Deleteing the EGR does absolutely nothing as far as performance. The only reason peeps do it is to clean up the bay a little.

1fast5.0 · October 30th, 2008, 09:46 PM

i didnt delete the egr for performance reasons i deleted the smog and ac for that reason and no i have true duals into super 44s into dumps and you tell me the carb wont help tell me why drag cars run carbs instead of efi

1fast5.0 · October 30th, 2008, 09:48 PM

and the egr has alot to do with the comp and it is miss reading for some reason if you would read and observe u would understand what i said

If you knew so much about the EGR and its workings then you would understand that your surging idle is a direct result of you removing it without turning its function of in the ECM. Until you do so you may never get rid of the surge.

You may have luck by adding a resistor to try and trick the ECM, but that is still just a bandaide.

I don't know how often you get out, but alot of race cars run EFI.

+1 you need to get it switched off in the computer otherwise the car will never run right. i've heard dealerships can do it for like $100, but don't quote me on that. or you can just put the EGR back on and wait till you get the carb and then just pull all that sh** out.

The only way he's going to go back to using it is to go back to EFI. He has nothing there for it to bolt to. Take it to a tuner and get it turned off.

WildWill · November 1st, 2008, 11:37 PM

oh i didn't think he had switched to carb yet... but +1

I agree. EFI is FAR superior to carbs, especially for street cars. Carbs are ok on race cars because they don't care about idle quality, part throttle drivability, and retuning for weather and elevation changes.

EGR is off at idle. It can cause part throttle surging, especially with wild cams. I would look for an air leak, or exhaust leak.

I dont think drag cars care about driving the car for more than 6 seconds and to them smelling like gasonline is cool.......what made you decide to go carb anyways? Are you manual or auto trans?

You would think that deleting the EGR would have a positive performance effect since there wouldn't be that extremely hot exhaust gas back into the Intake Manifold... But I could be wrong?
