I want to get rid of my emissons on my 86 mj

I want to get rid of all the emissions on my 2.8 because i don't need to pass emissions and they just annoy me. what can i remove without messing up things? has anyone done this before? does anyone have a vacuum diagram or emissions tubing diagram? will getting rid of them help my mpg? i would just like everything to be a little more simple.

 

thanks all

remove the cat and get some nice straight exhaust system with flowmaster muffler ;)

what about all of the random vacuum lines and charcoal canisters and stuff? if i cap off the lines will it be better or worse?

i suggest you to leave it. its will control fuel vapor from gas tank which its collect it and put it back to engine intake manifold

once upon a time I accidentally dislodged the charcoal canister line from the canister. I spent a few days chasing down a gasoline smell. :( Sorry to say, but most of the stuff in the engine bay does indeed have a real world purpose. :dunno:

 

the charcoal canister traps fumes that would have normally escaped from the tank and then the engine burns them later on, so technically the canister would increase mpgs, though by an infinitesimal amount. :D

agreed... if it aint broke don't fix it :thumbsup: can't get any easier than that.

 

If you pull it all out your gas mileage will go down a small amount and your gf/wife/date will be unhappy about the fact that your jeep smells like a rolling explosion waiting to happen ;)
