P0720 Output shaft speed sensor code?
I just replaced my starter and on my first ride after replacing it the X started to stumble a bit, and then would stall out at almost every stop light. It threw a CE light and I pulled the code P0720. I searched here and it seems most guys say this is a C.O.P. issue. If it is a bad C.O.P. would it stall like that?
I did have the battery disconnected but I made sure the terminals were clean and tight. Is this a coincidence or did I do something while changing the starter?

What was happening with me was the idle would drop and then stall, but I also had the P0722 also. Try some free things first: Clean your IAC and MAF first. If that doesn't do it then I would start looking at COP's.

For the archives, it was a bad C.O.P. as I thought. They replaced coil # 7 and a new plug it it runs great again.
