Did the Sea Foam treatment today. 1/3 for the brake booster hose, 1/3 for the crank, and saving the remainder 1/3 for the gas tank later when the tank is not that full. Went pretty smoothly, but didn't get much smoke at all like most people do. Only see a tiny bit, and I guess thats actually a good thing, meaning my MP3 engine is still pretty clean at 80K miles. I did get a CEL, as my dad pour the sea foam really slow, while I am reving the engine. It was fine at first, but the CEL went on about a minute later, when my dad is still pouring...yeah. He went really slow LOL. So looks like if you let the tube suck the sea foam real fast, its less likely the CEL to come on. But no biggy. Just need to disconnect the battery to reset and get rid of it.

Did you let the car set for a little bit after pooring into the booster vac line? My MSP smoked like a bat out of hell and it only had 59k on it when i did it. My Old P5 smoked pretty bad each time I did it to it(4 times full cans).
I did, right after my dad finish pouring, I let go the gas pedal and turned off the engine for 5-10 minutes, as instructed. Then start it back up and rev it for a few minutes (which is when I would expect a lot of smoke like others, but I barely got any...), then took it for a spin for about 20 miles. I got a couple rough start up, and idle was not as stable, but they slowly went away as I drive it more. It runs pretty normal by the end of that 20 mile drive, as well as the engine start ups as I need to move my cars around to make room for the MP3 into the garage. Maybe pouring/sucking very little bit by bit kept the engine from choking, producing less smoke? Not too sure really.

Try it again if you want. You can do it by yourself but let it poor in faster to the point the car dies and let it set for a little bit. You will have tons of smoke I swear.
I did this a while ago too.
My engine looked clean... even when I took the valve cover off right before doing an oil change, the oil in the head was amber clear, like new... not as chean in the crank case, but still not black.
It smoked like crazy, though, when I pourded in the seafoam.
I did it in a store parking lot, and the smoke was sto dense, it engulfed the near by restaurant.
I didn't really noticed any differences before or after doing it, but it was stil fun

I did this treatment, but with berrymans b12 instead. That has a following in the contour forums so i figured i'd give it a try. I ran a full can through with some in the crank case and half a can in the tank and after about 100 miles of driving its running so much better. Oil change friday and new plugs and wires and it'll be good to go.

Bump for Seafoam! Give some as a holiday gift!
The problem started a couple of months ago with CEL misfires in cylinder 3. I ran at least 2 bottles of techron and a couple bottles of the Shell version of techron through it with no change. I replaced both oxygen sensors and the EGR (~$450). Still no change. Over the weekend I started getting misfires in cyl 1 too. This morning (0* F) the idle was really really rough. Before sending off the injectors to be serviced, I thought I'd give this seafoam stuff a try.
I "sucked up" about 8 oz worth via the brake boost vac hose, turned it off and let it sit for 5 mins. When I started it up I got lots of smoke like most here reported. After about 2 mins, the idle evened out and the smoke stopped. Its running NEAR perfect. I'm going to finish up this tank of gas (poured the remainder in there) and see how it is then. Maybe I'll run a few more ozs through the vac line if its not fully cleared up.

Ok, I did the seafoam treatment last night on my 2003 Protege LX with 54k miles. The car is brand new to me and I was going to switch over to full synthetic anyway. So, I came across this thread and decided to try the Seafoam while I was at it. I followed the instructions here and put 2/3 bottle through the brake booster line. Put the rest in the oil. Boy did it smoke (steam?)! I did it in the parking lot at work and boy did I get a lot of weird looks. Great entertainment value if nothing else. I took it for a drive and cleared out the smoke. I immediately thought the idle was smoother and it ran great! I proceeded to change the oil. After changing the oil, I started it up and it ran fine at first. About 1/2 way home, it almost died at a stop light. The idle RPM dropped to about 300-400 and it continues to do it today. Every time I stop, the idle drops and the engine almost cuts out. Then it bucks and studders when trying to get going again. Once I'm up around 25mph it seems to run fine. Don't know what is wrong(dunno). Any suggestions?? Could I have fouled the plugs? Don't know where to start. I never did get a CEL during the whole process and still don't get one. Help!!!
