Why did you remove the evap canister? Might want to uncap the line that goes to the tank. Vent it somewhere.

a pencil???

holy cow I can barely breathe i'm laughing so hard here.....
good lord, that's so incredibly red-neck-ish! That's worse then my car when I bought it....

Yea, use rubber caps, pack of 10 is about $5.
If you don't use the evap canister I think your car starts to stink like gas, mine does and i'm thinking that's why....

lol

sounds like something my step-brother would do, for some reason he likes those self taping screws and uses them for everything.

Just out of curiosity, was it an 88 iroc painted blue with crappy spray bombs??? if so that was my step brothers...
May that car rest in peace

I'm removing those right now from my GTA. The reason you remove those is because they are basically useless and clutter the engine bay. When the charcoal canister is new it works to absorb and recirculate fumes back through the engine, but when it gets old the charcoal inside gets saturated and it serves no purpose but to sit there and take up space and weight.

The "pencil hole" is from what I can tell..a vent. Trace the hose that was originally connected there and see. If it goes to the canister its the intake from the canister for the fumes, if it goes to the valve cover then its just a breather.

The metal line you had capped off is your gas tank vent line. Don't plug that, instead get a length of rubber hose from the hardware store and run that line down inside the fender or something, but make sure it is facing down so no moisture or crap gets in there.

When you pulled all those hoses odds are you pulled the hoses that connect to the air injection lines to the exhaust manifolds and the cat. cap those off too until you remove the metal lines completely (which would look much nicer).

The other thing you can do is to pull the air pump which will free you up some horspower. On my L98 it is just below the AC compressor but Im not sure where it is on your motor, probably the same place but on yours it would be under the alternator.

question, couldn't you run the vent straight to the throttle body where the canister originally went? or would this cause problems?
