probably the break boster line.

i think u can do that in the break booster line... but don't go trying it yet till you get other answers cuz i'm not 100% sure. I never done it that way.. i just usually take out the air intake tube, open up throttle and spray some throttle body cleaner into throttle.

Yup, you can use the BRAKE booster line. Usually this is done using Seafoam but any cleaner should work. Pour the stuff into a cup and let the engine suck it up, kill the engine and let it sit for about a half an hour, then start up and enjoy the black cloud of smoke out your tailpipe. Drive and appreciate the newfound power.

Do you happen to know which line is the brake booster line ..

thanks

It's the 1.5 cm hose connected to the brake booster. The brake booster is the thick frisbee-sized dude with the master brake cylinder sticking out of it. It's under the hood on the driver's side of the firewall.
