I have an engine light on, and when I check it, it is PO 440 and specifically 441 and 446. I have done research and know it's evaporative emissions system and specially the purge flow and the vent control circuit. Any of you had this problem? I can't afford the mechanic charge and I'm not much of a mechanic. Any help on finding these items and fixing them on my truck would be appreciated. Btw, I bought a new gas cap, and it isn't that.
