2005 dodge ram
I had my truck checked and it said 6 and 8 misfire
and random misfire, can you tell me what that is?
It shakes when you reach 40 mph
How many miles on the truck? Around 100K, I would replace the spark plugs first. Then determine if the coils are actually bad. You can swap the coils from one cylinder to another and re-scan for codes to see if they move to that cylinder indicating a fault coil.
