Seafoam will help clean the carbon deposits out of your engine. It’s easy to use, and doesn’t take too long. You can find Seafoam at most auto parts stores. I think Wal-Mart sells it too.
Check out the video below to what I am describing. Start by having the engine warmed up. Shut the car off. Locate the brake assist vacuum hose that goes into the brake booster. The brake booster is usually located on the firewall on the passenger side. On my Honda Civic, I just used a pair of pliers to slide the clamp back, and removed the vacuum hose from the brake booster. Slide a funnel into the end of the vacuum line. Start the car and let it idle. Slowly pour Seafoam into vacuum line. You need to pour it in slowly so the car doesn’t stall. If the car stalls, just restart it, and continue. Continue pouring in the Seafoam until you have poured in half a can. Then shut off the car. Let the car sit for 10 minutes. While you are waiting, reconnect the vacuum line to the brake booster.
After the car has sat for 10 minutes, start the car. Rev the engine, and bring the RPM’s up. Smoke will start blowing out the exhaust pipe. This is the carbon leaving your engine. The more carbon, the more smoke. If you don’t have much carbon, you won’t have much smoke. Keep running the engine until the smoke subsides.
Now take the car out for a drive. Rev the engine. Accelerate up hills. Work the engine. Drive until the smoke disappears.
Pour the other half of the can of Seafoam into a full gas tank.
