engine repairs let's kick things off
0:14
with the basics the firing order for the
0:19
18726543 so what exactly does that mean
0:22

0:24

0:26

1:36
making it easier to maintain the proper
1:38
firing order as long as you connect them
1:40
correctly so why does this matter for
1:42
you ignition timing and firing order go
1:45
