Any problems with this? I'm lazy and don't feel like putting in my block plates right now...

 

1) Disconnect vacuum line from intake going back to EGR (disconnect at intake).

2) There should be a little rubber "cap" on the front side of the driver side wheel well in the engine compartment. Take this off (will expose point of screw) and use it to cap the open port on the intake. There... EGR disabled

lol, thanks Brent, very Marine like. (Work with what you've got)

I asked this same question if you could just unplug the line and cap off the port and didn't get a response.Do you think this does the same thing as actually blocking off the flow and does doing the line like this trip the code on 96 cars..??

 

As long as the EGR valve is sealing well, disabling the vacuum to it will make the valve act just like a block off plate. It will just sit there and do nothing. OBD-II cars like the 96-97 usually complain about EGR stuff more frequently than OBD-I cars do. So if you disable it, chances are good that you will get the SES lamp.

 

what the point? Why not just leave it active?

 

I seem to have a problem with it bogging sometimes when off idle and heard the egr can cause that so was thinking if doing this even temporary solves the problem then could get computer programmed to not have the light or get a new egr valve.

I think there is a tsb for defective egr anyone know if it applied to the 96 cars and if there is a new part number that fixed the problem.

 

I wondered the same thing... what are the gains in blocking it off? Does blocking the EGR, or dissabling it via the tube dicsonnection throw any codes?

 

your egr is probably bad, or partially stuck open. I'm a gm tech and we have problems like this on alot of the 4.3L vortec motors in say the jimmy/blazer, astro, and s10's. They will stick partially open and not close fully. From what i understand the EGR lets gasses recirculate under hard throttle. correct me if i'm wrong. But yea just plug the tubing, and unplug the egr.

 

I believe it only allows the gases to recirculate under part throttle/cruise.

Also, if you remove the valve/hose, it tends to make the gasket on the back of the intake last longer.

Yep, the MacGyver Fbody How-to Guide includes such helpful tasks as...

Using an ink pin to make a return spring

Making your own cold air kit from a supercharger intake

And more...



Hmm... My new "get rich quick" scheme?
