I was experiencing this same problem when I posted my original question (12/26/09). I replaced the IAC valve as suggested and the engine ran fine until this morning. The plugs and wires are less than 6 months old. The battery is about 1 moth old. There are no trouble codes present. The fuel and air filters were just replaced. The fuel presssure was checked on one of my many trips to the mechanic for the first problem and I was told it was OK (55psi).
have the same problem?
