carbon is from the fuel burning. There are additives you can add to your gas to help prevent this from happening or a good blast down the highway putting the gas to the floor and you might see some black smoke coming out of the exhaust thats carbon burning off. Carbon can build up if the car is driven easy all the time. or crappy gas doesnt help either. If the carbon is real bad it can start hanging valves open and make it run like ****.If it gets bad enough no power then would have to remove the valves to clean them.

pull the spout connector (a grey jumper located in the engine wiring harness either near the code reader port or the distributor) and put a timing light on the #1 spark plug wire. Aim the light at the pointer near the 10-o'clock position on the harmonic balancer (looking aft) while the engine is running and rotate the distributor until you see the pointer aiming at 8-10* BTDC. Don't forget to put the spout connector back in when you're done or else the computer won't be able to automatically advance the timing.
