Coming back from the river in my 06 LLY it would lag when I got on the gas, then all of a sudden it would take off like a sling shot (never use to do this). When I got home I turned it off to unload, went to grab dinner and check engine light came on. Scanner is reading code p2563-00 and p003a-00. Which one is the actuator and one is the sensor, do you think they both need to be replaced??
