As the title states, I have a friend that described the symptoms of a failing Camshaft Position Sensor on their 91 Buick Park Avenue, so I offered to replace it for them tomorrow at noon!!! I've been searching high and low for a guide online but haven't found one, I've read it's a fairly straight forward and easy to complete task so I'm hoping too much disasembly isn't required. I own 1000+ Craftsman sockets but I'm hoping it only takes 10 or less!!! Fortunately for them the sensor itself is only $30+ from Napa and I'm only charging them cost since they're exchange students who just bought the Buick to use for a year, so it would be nice to avoid buying an instruction manual too... Any help is appreciated as I am tight on time!!! Thanks!
