I have a 1994 Camry that recently developed a bug, it was stalling at idle. The service engine light came on so I took it to my Toyota machnic. He said that there were 4 codes showing and replaced the entire distributor, wires and plugs. He still had two codes showing but the car was running great. When my daughter got back to school she called me and said the car was still stalling but only when it is rainy outside. I called the mechanic and he suggested replacing the ECU. The Ditributor, wires, plugs and sensors he replaced cost $800 and I am reluctant to continue guessing at the problem. Anyone ever have a similar problem. If it was an old american car this would have been a hairline crack in the distrubutor cap or a bad plug wire.
