Pretty much, I'll be sitting at a light and it'll start to overheat and smoke, but if I give it some gas it'll be fine. It only happened twice this week, and it seemed to stop doing it as of today, *** my vac hoses are in the right place, so I'm thinking they might be loose or damaged, but idk for sure, any ideas?

 

does your fan turn on? system bled properly? t-stat installed correctly? start by bleeding the system properly then go from there
