Will removing emissions from a 95 throw an engine code?
Reason I'm wanting to remove emissions is because my car is running like crap and throwing an EVAP purge solenoid code. I've wanted to remove my emissions and install my EGR block off plate for quite some time, just never did because I was afraid it would throw an engine code.
Just need some insight/advice on this so I can make the right decision. I don't want my car to constantly have the CEL on...
Any insight/advice/comments would be appreciated. Thank you.

Yes it should defiantly through a code, thats what the CEL is for. It may go on and off sometimes. Unless your planning on getting a ecu tunning device ( dsm link, ecu plus, ect ) you should just fix the problem because egr block off isn't actually going to give any noticeable performance increase anyway. And if your doing it to clean up the engine bay.....I would rather have an egr valve than a CEL.
There are two ports on the canister, of which only one is hooked up from the factory as far as I can tell? and three hoses on the valve. The largest hose, which typically runs from the valve to the intake, is the one that carries fuel fumes, correct? Right now, I have this big hose that runs to the intake just pointing at the ground.
But, I took this picture:
There is a little hose that runs from this...thing...whatever it is, that ran up to the throttle body through the factory series of T's and little pipes. Can I disconnect this hose completely? I've disconnected everything else, but I want to make sure on this port, that it isn't expelling fumes or anything.
Well there is a line that is supposed to run to the canister down there, if you remove the canister like I did you have to CAP off the line if you dont then just cap off the canister otherwise you will be leaking gas fumes in the engine bay and thats not too safe :-\
I'm trying not to be too excited, because when I am, that's usually when something goes horribly wrong with my car, but I disconnected all the crap, pulled the solenoids off, capped the ports, etc, and the car gained somewhere between 1-2 inHG vacuum, which is nice, and my BOV is working phenomenally better than it was before. Now, even under light load and let off, I am not hearing any flutter like I was before. Cool. Plus my firewall looks much better than before, and now I realize I want a new intake manifold. lol.
Ok, so right now, I have the line from the gas tank still running into the canister, and I still have the line that runs from the canister up to the throttle body disconnected, just pointing at the ground. I also have the large hose that normally runs from the valve to the intake (large hose) pointed at the ground.
I've been doing a little reading, and things I'm seeing are saying that these ports/lines should not be blocked off, due to pressures caused in the gas tank. But, having them open means you're getting gas vapor in your engine bay, possibly igniting, or at least causing the car to smell like it has a gas leak.I have noticed a stronger gas smell since I pulled my lines.
