What is the difference between M20C and M20D engines?
1 Answers
M20C and M20D engines have no difference. M20 is the engine model, and the suffix refers to the manufacturer. M20C is a product produced by FAW Toyota, while M20D-FKS is produced by GAC Toyota. There is also an original imported version called M20A. The bore, stroke, and displacement of these three engines are exactly the same. Common causes of engine stalling faults: 1. Vacuum leakage in the intake pipe. 2. Idle speed instability caused by improper idle adjustment, dirty throttle body, or poor idle control system. 3. Unstable fuel pressure, such as excessive wear or poor contact of the electric fuel pump brush, or clogged fuel pump filter. 4. Blockage or bottom leakage of the exhaust gas recirculation valve.
