Programming to disable the 4-cylinder system DOD, MDS, AFM For cars: GM, CHRYSLER, DODGE, JEEP, RAM Most important benefits of disabling the system: - Longer lifespan for the car's lifters - The system causes higher than normal oil consumption - The system causes the car to shudder during acceleration at low speeds when it is active - Better throttle response for the car and reduced sluggishness - Better sound for people who have installed a cat-back exhaust or removed catalytic converters For your information, many workshops diagnose the car's shudder as a torque converter problem that needs replacement and gearbox overhaul. Or they diagnose it as a lifter problem that needs replacement without inspecting the engine or performing a computer diagnostic. Sometimes the check engine light comes on due to a misfire, and the main cause is the 4-cylinder system. When the system is disabled through programming, the car will return to normal, by the grace of God, without any problems. Service price: 149 SAR
