It could simply be your gas cap is loose or not sealing well. This happened on my 99 Toyota Sienna when we lost our cap. After replacing the cap the light went off. I got the advice from a certified Honda mechanic and is apparently a common problem.

After changing the plugs in a Toyota Previa Why would there be a lot of white smoke coming out of the tailpipe when the car is cold and stall when the car is in gear at a stop light?

White smoke indicates water indicates water in the mix! If your head gasket is ok then it could be you have upset the fuel mixture and you are burning too lean, the lambda sensors are getting upset with the exhaust fumes and then the engine management is unhappy and kills the engine when you stop (or chugs when you travel). Get it to a garage and have it tuned. i've got same problem with my '93 previa with 184,000 miles on it. i read somewhere the problem could be a sticky choke. will tell you more after i fix(hopefully) it sometime next week.
