you ever been drinin along pushed your clutch in to slow down and ur truck stalls out well it sucks and now my yotas doing it i've check the plugs and dist. all good and i have no vacum leaks any insight would be great my minds spent and i can't figure tis out. also the truck will idle when i'm just sitting there after the start up.
I had that happen after I did the headgasket on my truck a few years ago, it ended up just being a clogged vaccum line iirc.. I just don't remember which one. Mine started doing that in the first leg of a cross country trip and I ended up driving straight from CA to FL because I got sick of it dying where I'm about to get rundown by a semi with no room to move over.
