Question about 2003 Buick LeSabre
I have a 2003 buick lesabre and it's mishitting at high rpms. I changed the coils and the problem still there. I am thinking of having the feul filter changed and the plugs and wires have about 20000 miles on them. What do you think? Should I put new plugs and wires on even though they aren't that old?
You should take out the spark plugs and inspect to c their copndition, and then allow them to fire outside of the cylinder to also verify the condition of the firing. But make sure to clean the plugs and re-gap them.
