Alright, I need to order a new EGR valve from GM Parts Direct. Is the correct number 17113381 or 17113382. It is a 94 LT1 Vert A4 with 2.73's. Thanks!

 

17113381

 

how do you know it's that particular #? I guess I just wanted to ALSO know which years/options got which EGR #. Thanks though!

 

3382 shows for 95-97

 

cool, thanks dood

 

I thought the type of transmission mattered also.....I recall shoebox saying it's 3382 for an auto, but I'm not sure. Maybe he can clear that up.

 

1993 autos get 17113381
1993 6 speed get 17113373

All 1994s get 17113381

1995-1997 6 speed get 17113381
1995 auto w/federal emissions (NA5) get 17113381
1995 auto w/California emission (NB6) get 17113382

1996-1997 autos get 17113382

Clear as mud?

 

You da man, shoe!

 

Thread resurrection. I just purchased an EGR Valve off of Ebay, AC DELCO part # 19209963, Ebay part #ACDelco 214-5083. Is this part compatible for my 95 Z28 M6 car?

 

Yes.

 

Bringing this thread back...

What is the difference of A4 and M6 EGR-valves?
Some dealers don't list a difference and some do...
Could I run an EGR-valve for manual transmission also on an automatic car?

 

There can't be much difference, since one part # covers both manual and auto in some years. IDK what the specific difference actually is.

 

strange, they look identical from the outside at least
but take a look at this:
and even worse:

the first one is about what my actual valve is holding on vacuum…

 

I think it may have to do with differences in the exhaust back pressure, based on transmission.

 

what do you think about the vacuum -test on those two in the video?
