Do you need to clean the throttle for 40 thousand kilometers?

I plan to do maintenance these two days. Do I need to clean the throttle? I haven't washed my car since I bought it, and I haven't found anything shaking. In fact, ....................................................................................................................................................... can also do routine maintenance items, that is, change the oil and replace the machine filter. As for the air filter and air conditioning filter, it depends on the specific situation. If there is no smell, take it out and clean it up, and you can continue to use it. All other replacement parts are unnecessary, but they do not necessarily depend on the specific driving conditions. ! In general, it is necessary to clean the throttle valve. The specific performance is to hang the D gear and step on the brakes, and the car will appear obvious jitter. What's more serious is that when you step on the brakes, you turn off the engine directly. Maintenance items are for your reference: 1, oil change, mechanical filtration (the engine oil provided by 4S shop is sufficient); 2, clean the air filter, air conditioning filter (dirty replacement), check whether the brake fluid, antifreeze, booster oil is missing, not enough need to add; 3. Check the chassis and suspension parts for abnormal oil leakage and looseness (including tire pressure); 4, check whether all the lights are complete and good; 5, check the brake shoe wear; 6. Measure whether the battery voltage is normal; 7, clean the throttle, initialization; None of the projects recommended by the 8.4S store will be done (all are deceptive). I hope my answer is helpful to you! @20 19
