hey
i want to change plugs on a 97 b2300... the repair manual says leave it to a pro. is it that difficult? 8 plugs on a 4 cyl.

 

Just use the correct size spark plug socket, if you can get the connectors off the ends of the plugs readily and not mix anything up. So if there's access, pretty straightforward. Remember to check the gap on the new plugs before installing.
