How do I no if i have a bad coil on my 2004
if you have multiple coils then there will be a regular misfire on a particular cylinder. If you have sets of coils then the coil that handles a set of plugs will misfire on those plugs. If you have one coil to do the lot then indicators are engine will not start, coil lead will show a weak orange spark when sparked to metal, engine will start fine and run for a period of time before the coil overheats and starts to break down ( misfiring), coil is very hot to the touch (burning ) after minutes of operation.

Install three back spark plugs 2004 pontiac bonneville
there is a tool that replaces the dog bone upper motor mount that allows you to roll the engine forward which tilts the engine to give you more access to the rear plugs. you can also remove the upper mount and using a large bar roll the motor forward and block into place will do the same.
