ughh...i have a 2001 ranger 3.0 V6 with 135k on it. I have owned the truck for a while and the only major problem i encountered was a cracked head (got replaced). Late one day out of the blue my ranger started misfiring. So i broke out my code reader and found out i have misfires in cylinders 2 and 6. I replaced the spark plug wires, spark plugs, fuel filter and im about to dump 80 bucks onto a new coil pack. Im clearly out of options that i know of.
