Where did you put the seafoam? In the tank?

If you sucked it in a vacuum line, you need to change your spark plugs. If you put it in the fuel tank, don't worry about it, but there are better injector cleaners out there.

Keep us updated.

through a vaccuum line, but i pulled a plug afterwards and it looked ok, i just replaced them not to long ago with delco platniums...i can get them through work cheap enough so i guess it wouldn't hurt to do them again

I seafoamed once and didn't find any need after pulling a couple plugs to change them. I think that'* in extreme cases where dirt etc fouls them.

what is sea foam???

I've been through one tank and have noticed a slight improvement...between 23 and 24 mpg vs 19 or 20, but i didn't do my typical driving either, being near the end of the week/ begining of the weekend,, half my driving was around town on the weekend and i was stuck in traffic a few times. I will have better results by around wed. when i burn through this next tank.
