This video shows who to replace a bad ignition coil on a Chevrolet V-6 4.3L engine. The symptoms of a bad ignition coil are, the engine will not start, or runs rough. You can use an electrical testing meter to see if the coil is bad, but this part is only $20, so for me it was just as easy to remove and replace since it is such a cheap part (under $10 on Amazon if you want super cheap! http://amzn.to/25uT1zO
TOOL LIST TO REPLACE THE IGNITION COIL:
10mm Socket
Angle Grinder or Dremel
Small sockets and wrenches for the new bolt and nut for mounting bracket.
