Message I change the sensors (very hard to do at home), and the rich rotten egg exhaust smell went away. In hindsight the connectors may have lost contact. Since changing the sensors, I had a loss of connection at the TPS, which caused a very high idle. The connector looked clean, but it still lost connection. I have since inspected all connectors under the hood and packed them with silicone dielectric grease. Some connectors were very corroded (ones with the metal wire clips).
