Exploding Vacuum Hoses...help!
 

I finally got my girl running at a "good" idle (between 700 and 800), and even got her to stop overheating (temp is 1/4 of the way past C). But after driving her about a mile and a half I noticed that there is a hesitation and lack of power at higher rpm. I know about the ports, but I ALSO noticed that there is an exploded hose underneath the charcoal canister on the passenger side of the car. If you'll remember or better yet go look (READ: go trace the hose and see where it goes) there are 2 hoses that exit the bottom of this canister, well the left one (the one closest to the firewall) that's connected to the fender is done for! I need to know where this goes since I can't find the other end, and what it's for. Could this be the cause of my problem or...just anothe useless vacuum hose.

My car is an '86 GXL 2+2. Mods are as follows...

RP Online Catback Exhaust
Bonez TurboFlo System (not just the main cat)
Bonez Street-Comp Intake
Jacobs 8.5mm plug wires
NGK plugs
Secondary Throttle plates removed (shaft remains)

Well that's what I remember, but that's pretty much it.

...please?

It exploded? :D
Must've been rotted, did it explode or implode?

That hose is useless - it's just a vent for the charcoal canister. Over time, the heat will split the end of the hose, but it's no biggie.

Fumes from the gas tank go into the charcoal canister, where it is filtered and stored. In some conditions, the car can pull the vapors from the charcoal canister to burn 'em in the engine.

Reason being is, by law, cars can't have any evaporative emissions either - it has to be a closed system. Gas gives off fumes that are considered to be an evaporative emission, so auto makers store them and burn them in the engine.

The charcoal canister really does nothing as far as power, driveability, or fuel economy. Don't worry about it.

Not to be pickey, but wouldn't it be an implosion due to the vacuum? But thats besides the point... if its to the charcole canister, don't worry about it.

I'm pretty sure the car won't pass inspection if they notice the charcoal canister has imploded (sry) hoses on it. I'm sure I can hide it, BUT I would like to know what it's connected to if anyone else knows (a pic would help).

By the way thanks for the replies.

Your car will pass the visual, unless something else has been modded.

The hose simply dangles on the fenderwell.
