This car accelerate till 40 km, can't up more. Must release accelerate then will slowly speed up till 60 km, the same thing again. If accelerate harder, getting worse. No fault code come out.
1. Flush out the transmission twice, the fluid is clean now. No metal in it. But still the same.
2. Replaced fuel pump and relay, no improve.
3. Loose muffler and test drive, still the same.
