This is my Father's 1999 Toyota Camry with the 3.0 liter V6 (1MZ-FE) engine. About every three years, the Idle Air Control (IAC) valve always gets clogged up causing the car to keep stalling when cold started unless the accelerator was depressed while the engine warms up. It's expensive to replace (someone quoted my dad $300) but I read that a shot of carburetor cleaner down the hole usually takes care of the problem.
