Is it smoke or steam? and are you loosing coolant?
After you start it shut it back off and pull the spark plugs, see what color the tips are.
Also is your Cat plugged up? that would smell like sulfur if it is and you would be loosing power too.
Did Toyota use a vacuum modulator on their automatic trannys? If so and you have an auto this could make white smoke too.
Just some things to check.
Anybody else have any ideas?
