John, thank you for answering my question about the cam sensor. I went out to look for the engine number and I found this # 1823585C1. Is this the engine serial number? I am going to call international and get a spare sensor and want to sound like I no what I am talking about. Thank you so much for your help.

That's not the serial number. The serial number should be right below the plastic cover for the fuel bowl.
