I've attached a photo of what looks like a heat shield, which came away from the front of the exhaust. There is a white cable coming from the exhaust going to a greyish plug under the engine, which looks like the shield was covering. O2 sensor? Does this need replaced right away? Where can I get a replacement? or can I just forget about it, for now? Thanks in advance David
That part might be 17167-97209 - "Insulator exhaust manifold shield #1" The cable is, most likely, the pre-cat O2 / Lambda sensor. If it's the O2 sensor, you might get a check engine light when you run the car with it disconnected.
Number 6, thanks. The "O2 Sensor" cable is still connected so no check engine light. I really wondered if it would be ok to continue driving or will the cable melt pretty quickly without the heat shield for a wee while. I'll check out that part number though. Thanks. David
