Spirit R/T O2 sensor wire info
From a Daniel Stern email: That done, I decided to check on Bill's theory that an O2 sensor wire had perhaps been chafed and had shorted out. On the T3 engine, the 3-fingered starter-mounted bracket that Bill mentioned as holding these wires, doesn't exist. The wires run, in one of the ubiquitous black plastic convoluted looms, UNDER the air cleaner bracket which is directly above the exhaust manifold and turbo, and down to the O2 sensor. There was not one O2 sensor wire chafed or shorted. Not one, mind you--but ALL FOUR. Yes, all four wires had been quick-fried to a crackling, crunchy crisp and the cupric (cuprous?)-oxide strands remaining were all frazzled and mangled into one mass of seriously barbecued wire. It is plain to see that these wires had been too close to the turbo for WAY too long, and I just pulled the 3" section of bare wires into contact with each other or with the turbo when I disconnected the O2 sensor. Other R/T owners may want to pull the air cleaner and check the status of their four O2 sensor wires.
