Im out in the garage trying to get off the two bolts that clamp the EGR into the back of the intake, cuz im gonna block it off with a plate so that exhaust gas doesnt go into the intake, but it will still look like i have an egr, plus it wont take much work. However, im having extreme difficulties getting off the two of those bolts. Anyone have any input for me? I was trying to think of a better way to eliminate the EGR, but i figured that was the best way. Please help me out, i need to get rid of the bog and studder on my LT1

Do you know for certain that the EGR is the cause for your studdering. When I was searching for the cause of my hesitation/missfiring/studder, it turned out to be a dead O2 sensor. Nothing much is to be gained from removing the EGR anyway.

im already receiving code #32 which is the EGR, telling me its faulty. So i think my EGR is running open all the time or something....that is why i believe it is....

You'll have to use a open box end wrench, attack it from the drivers side, its tight be can be done, I think got 1 bolt from the drivers side and one from the pass side. I think its a 14mm maybe 15mm...

Took me about 20 mins....

Yep, the key is a boz end or open end wrench. I know I had tried with a socket, and struggled for a long time on it. Pulled out the box end wrench set and had it in less than 5 minutes.

I recall it being a 13mm. (But I wouldn't put money on it, my memory is terrible).

I've gotten the EGR code before. Turns out the pintle was gummed up with build-up, and keeping it from moving properly. I just took some WD-40 and sprayed on it, and moved it back and forth with my fingers. Then I checked all the vacuum lines to make sure they were in place, started it up, and the SES light hasn't come on since.

are u sure that we have the same two bolt sizes? Cuz i think i was able to fit a 1/2 inch on the bolt, which isnt metric...but maybe its supposed to be metric, i dont know.....

I used a 1/2 on mine. I blocked mine off too. Used a Dr Pepper can .

I had to use an open ended wrench. Didnt take long.

½" is the size of the nuts for the EGR valve and EGR pipe.
