the canister that goes to the trottle body and the EGR valve, it also has a line that controls the fuel (i think), i thought i read that somewhere, well anyway, how bad would this screw my performance up by eliminating it, and capping off all the lines? if that isn't going 2 work, is there anything else i can do instead?

Speed Kills - Drive a honda

i believe ogre's cave has information about it

should be referenced as a vapour cannister somewhere on his site

don't really know what it does myself but remember reading something about it there

You should be able to eliminate the canister by plugging the two vacuum lines from the TB and placing some sort of filter on the line coming from the tank...you also need to keep this line as high as possible, otherwise gas can flow thru it from the tank

The canister is designed to improve gas mileage by making use of the gas vapors in the system.

There is charcoal inside the canister and it can go bad after age or being soaked with gas...also there is a filter on the bottom of the can that can get clogged.

Good Luck

The Fiero has a charcoal canister next to the air filter. But there is a vapor canister on the other side of the car too. It is under the rear clip beside the battery. It is hard to get to but you can see it if you take out the right side wheel and inner fender or if you take out the fiberglass inselation that is next to the battery.
DONT take this stuff out. The charcoal canister and vapor canister work together to recycle gas vapors that form in the tank from heat and sloshing around. How do you plan on venting the tank. That could be a fire hazard if you dont do it right, raw gas fumes venting out at will and uncontrold can be kind of dangerous. The tank needs to vent even when the car is not runnig. The outside temp causes the gas to evaporate, and that is why the two canisters are there.

This is the Fiero charcoal canister and the Fiero vapor canister

This is the vapor canister and charcoal canister that I used to replace the Fiero canisters on my 3.5 conversion.
