I recommend that you replace the spark plugs,the fuel filter,the air filter,the pcv valve.the spark plug wires on this truck are not known for failure but are cheap insurance.I also recommend that wou clean the throttle body and have the fuel injectors professionaly cleaned.This will last another 100000 miles
