What is the point of taking of the EGR and putting the EGR passage cover plate there?

 

NO ONE KNOWS? im at that point where i have taken all that **** out and as long as i got half my friggin engine apart i would like to know now. Instead of day after i put all that **** back together.

 

The EGR valve tends to go bad after a while. It routes exhaust gases back into the intake. If you remove it then that won't happen anymore.

 

I have heard that u will gain hp from either disconnecting it or just plain taking it off. I heard this from a lot of ppl. does anyone know for sure?

 

If you have everything apart you should remove it. It's just for emmissions.

 

There is a vacuum hose or some type of other hose that connects the EGR to the intake. Do i need to plug that hose? And does anyone know where I could buy vacuum hose nozzle plugs. The Rx-7s have some of them stock on some places where there could be an option but i didn't get the option.

 

Easiest thing to use to plug a vacuum hose is a screw or bolt. EGR is just a reliability thing. I doubt it would gain you any noticable horsepower, and removing it will probably lower your gas mileage a tad. However if the EGR fails, you may start having strange idle and stalling problems, that is why most people remove it. I had my EGR fail on my MX-6 (actually is was the mechanic, he plugged a vacuum hose which caused the valve to be continuously open), and I would have very strange low idle, and if I wasn't careful coming to a stop my car would usually stall. Leave it, or remove it, in the end it you probably won't notice the difference.

 

I took it off and put the block off plate over the egr passage. There is an open vacuum nozel of the intake where the egr connected to DO i need to plug that????

 

Yes, you need to plug that hose. Check out the HELP section at Pep Boys. They sell vacuum caps.
