Question about using seafoam
 

Hey guys, I am going to be using some spray sea foam on my 2005 Ford E-250 (105K miles). Getting to the throttle body is a bit of work so I was wondering if I really need to go all the way to the throttle plate or if I just need to be past the MAF sensor? If I recall correctly, the MAF sensor is further upstream and if all I need to do is go past that it would make it much easier. Let me know what you guys think! Thanks!

Would you care to enlighten us as to what kind of problem the vehicle is displaying that you hope Seafoam will correct?

no problems, just wanting to keep things clean. I bought the van used and am not sure how it was treated before so I am trying to make sure I keep it in good shape.

Have you considered treating it to a tankful of premium every so often.
Gets into a little bit of chemistry that we don't need to go there now.
