My hose that goes to the manifold, the one that connects to the evap purge control solenoid valve is gone. I plugged the hose plug in on the throttle body with a lil plastic piece. But with that being plugged will it make the car run like shyt or alter the performance in anyway.

 

No, I took my charcoal canister completely out and no difference whatsoever...

 

I have a 92 prelude DOHC vtec with magnaflow exhaust,dc headers,AEM intake,ngk ignition wires and ive ran it twice all i can pull in the 1/4 is 15 is that decent, or old age playing a part in why its running so slow. I launch off at about 4k if thats to any help.
