evap solenoid code

EVAP solenoid circuit  Harness and connector / EVAP solenoid 
Evaporatice purge flow monitor failure (M/T)  Evaporative purge solenoid / Clogged purge line / Vacuum hose / Evaporative emission canister clogged 


That can explain the gas smell, but the stalling leads me to believe it is the coolant temp sensor.

I had this code a couple of months ago.  I found that the solution was as simple as reattaching a small rubber hose which had come disconnected from the EGR valve in the back of the engine.  I think that there are two hoses that go into the valve itself coming from the EGR solenoid, and two that go from the solenoid into the intake plenum.  Just make a quick check to ensure that they are connected.  This may not be your problem but hey, it's quick, and it's free.
