1. Check the spark plugs and wires. Worn or damaged spark plugs or wires can cause the engine to misfire, which can lead to stuttering and kicking. Replace any spark plugs or wires that are in poor condition.
2. Clean the throttle body. A dirty throttle body can cause the engine to idle rough and stall. Clean the throttle body with a throttle body cleaner and a rag.
3. Check the fuel filter. A clogged fuel filter can restrict the flow of fuel to the engine, which can cause stuttering and kicking. Replace the fuel filter if it is clogged.
4. Check the transmission fluid level. Low transmission fluid can cause the transmission to slip, which can lead to stuttering and kicking. Add transmission fluid to the correct level if it is low.
5. Have the transmission inspected. If none of the above solutions resolve the problem, the transmission may need to be inspected by a qualified mechanic. There may be a problem with the transmission solenoid or torque converter.
It's important to note that attempting to fix an Acura Legend's stuttering and kicking problem on your own can be dangerous. If you are not comfortable with automotive repairs, it is best to consult with a qualified mechanic.
