Wondering if anyone can point me in the right direction to solve my ses light. When i pull the code the description "EVAP system flow during non-purge". I forgot to write down the code number just hoping someone on here has an idea of what is up with this it is now causing the truck to act as if it is either flooded or starving for fuel but only when stopped at a light after driving. thanks for the help

Also wonderin if anyone as experienced a cold draft while driving. Its only on the passenger side of the pickup comes from under the dash but i can't seem to find it.

Was the trouble code P1441? If so, it failed the purge valve leak test, i.e., there was vacuum in the fuel tank with the purge solenoid valve closed. I may cause starting problems but usually no driveability problems. On the "cold draft," I've no idea.

Could this be caused by a bad purge solenoid? or something else.

It could be the purge valve itself or control circuit. The former is easy to tell if you have a vacuum gauge. Take the electrical connector and purge pipe (the vapor line that goes toward the fuel tank) off the purge valve, hook up the vacuum gauge, and then monitor the vacuum level with the engine on. If the valve is leaking, the vacuum level will rise.
