Yeah the port was clogged, and I went in through the throttle plate and cleaned it out. The misfiring was due to spark plug wires. I changed the spark plugs, and the oil, and sold the car to a friend of mine. I got a guy at AutoZone to let me borrow his scanner so that I could clear the codes. My friend said the check engine light came back on again. She's suppose to go have it checked out, and then I'm going to continue fixing the car for her. Thank you guys for all your help!
