If I want to change Spark plugs do I have to replace coil pack too
My Holden vectors is 2001 2.6 v6 is spluttering and has no power when I take off and
looses power going uphill severely to point it don't make it up steep hills at all unless in
1st gear I been told may have bloked injectors or spark plugs may need replacing and if
they do I'll have to replace coil pack aswell is any off this true and could it possibly be any
of these things that's the prob
