I’ve been having some issues with the Jeep not running right, all traced back to the throttle position sensor going bad, so I pulled it off today to replace it with the shiny new one I picked up yesterday.  Unfortunately, one of the two bolts had a different idea and sheared off, leaving about a 1/4″ nub sticking out of it’s hole in the throttle body.  I could not persuade it to move, so I’m going to take a break and tackle it later.  Thankfully I’ve got a second vehicle to get around on…
