Me and a friend decided to sea foam my car the other day, and what a DIFFERENCE. I've heard of the stuff forever, but I've never used it. Basically it's just a carbon eliminator liquid in a can. It more or less steam cleans your engine, cleans your valves, cylinder heads, flushes your injectors....gets rid of all that carbon build up. First, warm up your engine, then turn it off. Have one person take the vacuum hose off the brake booster, and stick his thumb over the hose. Open can. Have the second person start the car. First person will then quickly insert the hose into the can so to induct the cleaner into the intake system. The car will want to stall while it sucks the sea foam down, so the person inside the car will want to give it some gas. After the can is empty, shut the car off. Reconnect hose. Wait 5 minutes. Then restart the car and drive it on the road...because it will smoke...A LOT. After about 5 minutes of smoking, the engine will have run the sea foam through and you will be able to notice a huge difference in throttle response and acceleration. The can costs under $6 from an auto parts store and takes 10 mins to do. This is what jiffy lube and the dealer turn into $80 using weaker stuff.
HIGHLY recommended!
EDIT: I see seafoam going for roughly $9-10 per can now.
