Your local auto parts store should have this stuff called "seafoam". It kinda works like all those other things that say they will "clean your engine" and all that crap, but this stuff actually works. Its funny like that, the stuff that always works, you never see an advertisement for (when was the last time you saw an ad for PB blaster?).Anyway, buy a can of that stuff. Pour half the can into your gas tank, drive around a little bit. After a day or so or whatever other decent ammount of driving, use the rest of the can through the brake booster vacuum line. This might take 2 people to keep the car running. When it has sucked it all up, shut the car off for about 10 minutes and go get a gas mask and a video camera (optional). Come back after 10 minutes and start the car. When it starts (it might be rough), DRIVE THE ABSOLUTE PISS OUT OF IT. Make sure you are in a well ventalated area, preferibly not near any significant area of population or where it might cause an accident, cos this **** will be the craziest smoke screen you will ever see. After maybe 20 minutes of driving, your car should be pretty damn clean of any junk, and if you are lucky it will have cleaned your EGR system out too. Afterwards you'll be wise to change your plugs and O2 sensor.
Any other questions about seafoam, or other's experiences can be found through a simple search on here.
