Signed up to post this, because I can't believe this is true.

I bought an '06 Expedition at auction last month. I got seduced by the 9/10 body, paint almost perfect, and the clean interior, decent mileage at 200k km. I paid $3500 Cdn for it which is about $17.25 USD.

Now with this particular auction, you can inspect the car, but you are not allowed to run a scanner on it or start it. If I had, I would have passed on this Expy. I took possession of the truck, started it up and...uh oh. CEL, a constellation of lights all over the dash. It ran like crap, no power, bucking, terrible mileage, stinking exhaust, hard to start. I drove it home and determined that it had a bad battery, replaced the battery which fixed 80% of the lights on the dash. The scanner gave me the dreaded Cylinder Misfire and Bank 1 Too Rich, and I started pricing out new coils and plugs on ebay and resigning myself to a few hundred dollars of labour to swap out the plugs and coils (I read the spark plug TSB and I was like, nope, not gonna do that)

Then I found the thread here about SeaFoam and I figured, what the hell, I was going to Canadian Tire anyways so I'll throw it in, what's the worst that could happen? I bought a can, then SeaFoam'd it in the parking lot, some in the crankcase, some in the gas tank, some up the vaccuum tube.

It didn't seem to make any difference, except now it was smoking out the exhaust, so I drove around for about 20 minutes, kind of giggling about the smokeshow. I pulled up to a stoplight, expecting it to shudder like a ******* wanting to stall. In fact I thought it did stall, because there was no vibration from the engine at all. In fact, it had smoothed itself out perfectly and was running like a top. Then I looked down. The CEL had gone out! Ran the scanner, all of the misfires had cleared!

Took it for a run out on the highway and did some WOT runs. It bucked a couple of times, then I drove it back home. It drove perfect! Tons of power! I let it idle for a half hour outside my house, then looked at the exhaust pipe. It was spattered with greasy carbon and dripping a little. OMG, I said to myself, this stuff works!

Time will tell, I thought. So, I've been running it for a week and it responds and behaves like new. It starts the first time, every time. I have no idea how this product works, but for $13 Cdn, this product is going to allow me to defer the plug maintenance for a while, and in the meanwhile, I have a working truck. Darn thing runs like a top now. I'm sold, I'm putting it into my F150 this weekend.

 

Yeah sometimes you get lucky ! I've had good results with it running through the crankcase before an oil change too. It's awesome in yard equipment keeping them in good running condition.

Seafoam can do some good things for you if a dirty fuel system is the problem. There are a few others that work well too, but seafoam is a standby of mine.

Glad it worked out for you
