I think my EGR valve went i keep gettin a code 32 and checked all the connectons and reset the computer and the SES light still comes on is there a way i can tell if its bad ofr sure??? also is there a way i can bypass it for a while til i get around to putting a new one in they run min of 220.00$$

 

This is the best and only way to tell if you have a bad EGR valve. Spray WD-40 at the base of the EGR valve while the car is running. If it sucks the WD-40 in then our EGR is leaking and bad. Quick and easy. Later bro

what exactly does the EGR do and am i doin anydamage with the code 32??? also is there a way i can take out the EGR and put resistors int the connector til i can get a new one? I have the mney i just dont see the use in it really and dont wana spend the cash right now...

 

Oh ya do they sell any kind of high performance EGR valve ive seen some moded and the dude said he gaine like 5 HP buy cutting off some stem

 

Nobody sells a hi-po EGR. EGR only activates at high-speed, low-rpm "cruising" conditions, when the car is warmed up. Therefore it doesn't affect HP when you floor the gas. and if you're cruising (low rpm) you wouldn't use the extra HP anyway. That whole "block off the EGR!" or "disconnected EGR" thing is a load of bull... the only way someone gets faster from that is if either (A) their EGR was stuck open and always working, or (B) they have a good imagination.

I saw the thing on LS1. com i think it was a modifactation on there page

 

Does this sound like the asket i sprayed WD40 and saw bubbles forming in 2 corners were the gasket it is. So is this a bad gasket i was gonna buy some orange permatex and sue that around it to seal it off.. would that work and is that the problem.

 

Could be, but which gasket did you put the sealer on? The EGR-to-exhaust-manifold gasket, or the EGR-tube-to-throttle-body one?

I ask because a leak on the EGR-to-manifold gasket wouldn't be "too" bad. Since EGR doesn't work all the time, you wouldn't notice a problem all the time. If the EGR is closed, a leak in that spot is "just" an exhaust leak... know what I mean?

But if the leak's at the EGR-to-TB gasket, the leak is always affecting the motor.

One thing I just noticed- code 32... that should come from the vacuum switch. The computer just knows if the EGR valve gets vacuum or not; it doesn't know if the EGR reacts to the vacuum or not. It could be a cracked vacuum hose- the computer activates EGR, then "sees" no vacuum because of the leak, so it sets an error code.

Oops, wait, is that an electronic EGR valve? Or is it vacuum operated (hose going to top)? If it's electronic, then ignore my previous paragraph- I don't know how the electronic units work with the computer.

its a Digial EGR... the ligt would aways come on when i wa passing soemone doin around 70 or getting off the freeway but the conector on it is shot to hell.. and they dont sell connectors for it and ive been to 6 boneyards yet to find one with a ditial EGR connector and when i looked at the seal i took off it was the one between the exhaust manafold and EGR at the base of it in 2 spots were i saw some small hoes at i saw carboon buildup on the outside and those were the 2 spots that were bubling with WD-40

 

The "EGR tube mod"...That is on LS1 motors and there is an EGR pipe that runs into the middle of the air stream behind the throttle body. You cut this off and get a gain....As far as 5hp, Hmmmm

TomP is right on the money here.....I love people saying they gained (insert # here) Horsepower by disconnecting the EGR.....Yeh right.

I find EGR valves at the Pick U Part yard in Santa Paula, Ca for $4.00 each. You must find the same model number as your car.

 

DR ross were in westlkae do you live i live in simi vally like 5 mins away

 

when are you getting this code 32? how often? im guessing once in awhile driving at highway speeds, usually decellerating a bit?

 

i normaly get it when passing or decelerating... i took it to my friends shop today and he has a tool to hook up to the EGR well we get there and pop the hood the connector is out i know for a fact it was in this morning ive had a problem with the connector about a year ago but anyway he hooks it up EGR is fine the connector is corroded and the plastic is comming off of it so i need a new connector.. Were im gonna find one i dono ive gone to 7 bone yards still cant find it and to get a new one i need to buy a new EGR not gonna do that... But the thing i dont get when i check the connector and put it back on i still had the SES light on

 

Is this the connector on the wiring harness? You can find those at "big" auto parts stores, they're made by Motormite.

I checked Napa autozone pepboys and the GM dealership they didnt have the kind i needed also the thirdgen catalofg i have didnt have the connector it had all the connectors except the one i needed... hopefuly its not rainging tommorw so i can go to the boneyards again... any one ever feel sad when the go to the boneyard and see all the 3rdgens that will never see the streets again

 

ahh.. what i was getting at was the egr solenoid, but the connector being loose/corroded would do the same thing.. yeah i hate seeing fbods in the yard, a lot of cars with potential.. my one local yard, only have one fbody, a 84 2.8 maro.. pretty much everything missing off of it, i have taken.. so its pretty much my #1 donor..

 

FastRS, what does the connector look like? I found a 5-pin MAF connector for some people on the main tech board, and they swore the same thing you're saying (that it doesn't exist), maybe I can get lucky twice!

Are the pins on the connector large-ish and round and separate? (Looks like: o o o ) Or, are they small-ish, square, and all linked together? (Looks like ::::: )

Well i have the connector now i took 2 its a 4 pin connector
think of it as being a triangle and the back has 2 square conectors in it the front has one in it and in the middle it had one
