I'm thinking about doing a Seafoam treatment to my truck. I'm just a little reluctant. The damn thing has been running funny lately, and I think I have a carbon build-up issue. She'll run rough as hell when she's cold, and then smooth out after she warms up.This could be my EGR valve acting up. Any ideas?
its an easy thing to clean, just ask gramps he just did his, and i don`t beleive they are all theat much different, his looked just like mine, anther thing is to check for vacuum leaks. are the plugs/cap/rotor/wires fairly new?
