where is it? i really feel stupid for having to ask did a search and came up with nothing. my truck just hit 28,000 miles so i was thinkin about tryin out the seafoam.

 

nm, got it figured out

 

so i did the seafoam today and now my engine puts off a vibration in the lower rpm's. you can really feel it when you play with the throttle body by hand. its annoying the hell outa me because i can feel it in my gas peddal and it makes something in my firewall rattle. how do i stop this?

i ran a can of seafoam in the gas, and about 1/3 can through the brake booster line.

 

problem solved. just needed a bit more foam thats all

 

Seafoam is awesome, I recommend it to everyone. Really helps a lot.
